I have never seen such problems, and neither did anyone else complained about
this, ever.

If this phenomenon happens only in certain program(s) (as opposed to _all_
DJGPP programs, including those you download from SimTel), I'd first suspect
some subtle bug in the program.

So please describe what does the affected program(s) do when they exit.  For
that matter, please describe the procedure to reproduce the problem (pressing
a key during a split second sounds pretty tricky, especially on fast
machines).

Also, please elaborate what do you mean by ``Windows 95 in DOS mode''.  Do
you boot into plain DOS mode, without loading the GUI part of Windows, or do
you switch to DOS Mode *from inside* Windows.  Or maybe you run the program
from the Windows DOS box?

I'm not convinced this is a problem in the library.  Without good
understanding of the problem particulars, nobody will be able to tell you how
to fix it.  Granted, if the development team knew about this problem, it
would have been fixed.
