--- Comment #16 from Hin-Tak Leung htl10@users.sourceforge.net 2008-04-08 20:30:00 --- F1 works for me (and I can run the apps alright, I think - I am not a pole, can't do a thing with it), although wine crashes on exit (probably different problem) With wine git.
It is also curious that some help page is blank (only a couple) but I guess it is something to do with unimplemented graphics, and anyway, I can't read polish and don't know what's supposed to be missing.
You seem to be right on the +2 double-null terminate.
