Main problem with debugging is that this is a graphic application
and the problem is related to displaying a mouse cursor.
I am no gdb guru either but to my experience it isn't that easy to
debug such programs with gdb. (At least I always managed to avoid it.)

I've stopped graphic programming years ago. All my newer programs
are text interface oriented and most of them commandline only.
Life's much easier that way. 
My current problem is that someone requested a new feature in a 6 year
old program. The new feature itself wasn't that complicated but
it took a day to get the whole thing running because of that library 
problem.

BTW: I was impressed that this graphic application also works
with WinNT 4.0 now.
