Several users have reported that their systems crashed or hung really bad
when they opened folder content menus.
From their reports I suspect that the problem lies
in some video drivers (at least those of the Matrox Millenium -- seems that it's got
the Year-2000 problem built into the name, haha), and XFolder gets messed up showing
the icons in "folder content" menus. This is why showing icons is now turned off
per default.
Ralph Scharpf had the same problem and reported that one could install the IBM
GRADD drivers for MGA video cards instead, which appears to be working. Unfortunately,
those cards do not support 1024x768 with more than 60 Hz, but if you can live with
800x600, this appears to be a solution.
