I've found a problem with the WIN-OS/2 printer driver that I'm using with my printer? How do I get an updated version of the driver? A. The WIN-OS/2 drivers were not written by IBM, but are licensed for inclusion in OS/2. If you need a driver update IBM might be able to obtain it for you, but you'll get it much quicker if you contact the supplier directly. Q. How do I run WIN-OS/2 in real mode? Can I run WIN-OS/2 in 386 enhanced mode? A. Type 'winos2 /r' from an OS/2 'DOS Full Screen' session, or put '/r' in the parameters held for an OS/2 shell object. WIN-OS/2 doesn't support enhanced mode and applications that require enhanced mode will not run. Q. Why won't ScanMan and FotoTouch run under WIN-OS/2? A. They both make a 4B interrupt call to create a DOS thread. This isn't currently supported. Logitech scanning hardware is normally used by WIN-OS/2 applications running in real mode. Note that Ansel (Fototouch's predecessor) will work in real mode. Q. I get DOS Error 5 when I try to run some of my Windows applications under WIN-OS/2? What do I do? A. Boot from OS/2 boot disk, insert disk 1 when prompted. When you get OS/2 Welcome screen press ESC. Insert disk 2 and type A:CHKDSK C: /F (FAT) or /F:3 (HPFS) where 'C:' is the drive OS/2 was installed to. Repeat CHKDSK until it runs without any errors. Q. How do I start multiple WIN-OS/2 applications from the same OS/2 desktop icon? A. Drag a program object from the Templates folder. Set Program to '*', set Path to full path names separated by commas for programs that you want to start. See Master Help Index - WIN-OS/2 for more information. First program listed is incorrectly started twice. Q. I have the Canadian version of WordPerfect 5.1, how do I run FIXWP? A. FIXWP (see OS/2 readme) doesn't work for the Canadian version. Call WordPerfect and ask for interim release. Q. SHIFT-ESC doesn't seem to do anything under WIN-OS/2. This means certain programs (see Attachmate under Applications) can't be run. Is there a fix? A. A keyboard bypass option for SHIFT-ESC needs to be added to WIN- OS/2 and DOS settings for CUA (Common User Access) compatibility. Q. I Get FATAL ERROR 0X0401 trying to start a Windows application in a WIN-OS/2 session. What can I do? A. This problem is caused by one or more of the drivers or font files listed in the WIN-OS/2 SYSTEM.INI or WIN.INI file being absent or not loading correctly. This can happen if the application migration/installation was incomplete/incorrect. Check device statements, or re-install application from WIN-OS/2 Full Screen. This error has also occurred on systems running in XGA or 8514 video mode when an application tries to use large fonts. It might be necessary to modify the WIN-OS/2 SYSTEM.INI file as follows; fonts.fon= xgasys.fon, fixedfon.fon= xgafix.fon, oemfonts.fon= xgaoem.fon. Q. I have an 8514 display and am having trouble using DDE with WIN-OS/2. What's the fix? A. If you have an 8514 display use DOS Settings to set VIDEO_8514A_XGA_IOTRAP to Off and VIDEO_SWITCH_NOTIFICATION to On. Q. Data I put in the OS/2 clipboard doesn't show up in the WIN-OS/2 clipboard. What could be causing this? A. Because of the particular data format there may be a rendering problem that prevents the reception of the data from the WIN-OS/2 clipboard by the WIN-OS/2 application. A private data format used by one application could be unusable by another. WIN-OS/2 clipboard issues are covered in a similar document to this one. Q. I'm using the EPSON.DRV WIN-OS/2 printer driver and I get duplicate form feeds, can I disable form feeds? A. The EPSON.DRV driver doesn't provide disable form feed or intelligent form feed options. If this causes you a problem you'll need to select another driver that works for your printer. Q. Every few pages my HP DeskJet 500C color printer prints a whole page condensed to slightly more than 'thumbnail' size. How can I fix this? A. You need to add [STATDLL] override=y to WIN-OS/2 WIN.INI file. Read the read.me file for your DeskJet printer. This file is located on the first of the DeskJet driver installation diskettes. Q. Sometimes when I switch sessions from the OS/2 Desktop back to WIN-OS/2 using the ALT-ESC option I find that I have no mouse pointer. Is this a known problem? A. This problem has been reported and logged. Simply repeat the ALT- ESC sequence to recover the pointer. MAIN SECTION ============ Seamless WIN-OS/2 Q. What is the difference between a seamless and a non-seamless application? Are there any problems running Windows applications seamlessly? A. First realize that the way an application is started (double-click on the application icon on the desktop) is the same whether the application is set to run seamlessly or non-seamlessly. When a Windows application is started it is seamless if it starts as a window on the OS/2 desktop (imagine the Windows application starting up and 'punching a hole in the desktop' so that the application window can be displayed) . It is non-seamless if clicking on the application icon on the desktop first starts a WIN-OS/2 DOS session, and then starts the application from this new session. In this case the OS/2 desktop has been replaced with WIN-OS/2 Full Screen (imagine running Windows 3.0) and the application is running within a complete Windows environment. When the user closes the application, the Windows session is automatically terminated, and the OS/2 desktop is re-displayed. When applications are migrated to the desktop (Setup - Migrate Applications from the OS/2 System Folder) they are configured to run seamlessly. It is a simple matter to change them to run non-seamlessly (click on application icon with right mouse button, click on open, click on settings, click on session, click on WIN-OS/2 Full Screen). Running windows seamlessly is a complicated thing for OS/2 to do internally. The known seamless problems at this time are: - occasional unexpected loss of focus, for example when running Word for Windows seamlessly. Use the left mouse button to restore focus. - no Windows applications are running at shutdown, but upon reboot show up cross-hatched (as if they were running when the machine was shut down). Correct by closing WIN-OS/2 session from window list. Press CTRL-ESC then use right mouse button to close. - OS/2 gets confused when more than one Windows application is running. Selecting an application from the window list (press CTRL- ESC) results in the wrong application being selected. Correct by changing session parameters for the applications. Do this by clicking on application icon with right mouse button, click on open arrow, select settings, select session, then click on 'Separate Session' check box. Q. My display is not VGA. Can I run my Windows applications in seamless windows? A. You will not be able to run seamless windows unless you are running OS/2 in VGA mode (or XGA mode with the Video Upgrade package). Q. Why can't I override the system setting for 'Minimize To' behavior for my seamless windows applications? A. This is a known problem and has been fixed for the first service release. Q. I created a document icon called 'WordPerfect Document' with an association to my WordPerfect program. I double-clicked on the icon and WordPerfect started up. After I had finished with the document I closed it. When the icon reappeared the name had changed to 'WordPerf'. What went wrong? A. WordPerfect doesn't support Extended Attributes (EA's) and when it saves a file to disk any EA's that existed for that file are lost. The same problem will occur with all Windows applications. The workaround is to save the extended attributes of the file (using EAUTIL /S) before loading it and to reattach them to the file after the program has exited (using EAUTIL /J). This may be done using REXX. This approach will have even more potential when REXX is enhanced to support manipulation of Workplace Shell objects. Full Screen WIN-OS/2 Q. I have changed the settings for my Windows application icon so that the application runs in a WIN-OS/2 Full Screen session. Now when I close the application I am left with a blank screen, except for an icon named 'Desktop' in the bottom left-hand corner of the screen. What is wrong? A. This usually happens if a 'Help' window is opened and never closed while the application is running. This is a WIN-OS/2 problem rather than an application problem. Click on the 'Desktop' icon to get back to the OS/2 desktop and delete the application from the window list to terminate the WIN-OS/2 session.
