Yes, the program should run in Linux too.

I tried to set my NT display to 1024x768 with 256 colors, but then xfree
crashed when started. It seems that it doesn't start the vtwm at all, it
just gives the xterm "empty envelope", but you can't move it and when
clicking the left, xfree vanishes and you are back in the Windows. It
crashed even when I didn't start the vtwm. 

However when I set xfree to 800x600x8, it started and the program displayed
5 differently coloured upper task bars with black screens (when clicking the
right) instead of 2 as before. So we are going forward!

Then I set the Windows in 800x600x8 too, but again xfree didn't work.

I don't use Test 7. I have some version of cygwin (1.1.4+) and then I have
the following packages:
devel, DLLs, fonts, Prog, rgb, Xterm, Xwin.

Some more ideas?
