Current mouse and pm3d patches for gnuplot sources are no more stored
on this site. Please get the sources from gnuplot's SourceForge CVS tree:
under OS/2, you can edit and run the following getgnuplot.cmd:

  setlocal
  set HOME=.
  SET CVSROOT=:pserver:anonymous@cvs.gnuplot.sourceforge.net:/cvsroot/gnuplot
  cvs login      .... use <ENTER> when asked for password
  cvs -z3 checkout -P gnuplot
  endlocal

You can get the "latest" OS/2 precompiled binaries, which include mousing 
for PM and X11 as well as pm3d, from this site; see
	gp38i-DATE-os2bin.zip
Also the Windows binary is available:
	gp38i-DATE_winbin.zip

Please, notice that the "latest precompiled binaries" are *always* older than 
the current development sources, so if you notice any problem, please get
and recompile up-to-date gnuplot yourself; see also gnuplot ChangeLog:
     http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gnuplot/gnuplot/ChangeLog
