I have been attempting to get a resident program working with programs
that use dos/4gw (v1.97).  The problem is finding a dpmi host that is
compatible with both djgpp programs and dos/4gw programs (I'd rather not
use the Windows dpmi server).  Using cwsdpmi (r3), some programs seem to
work fine (such as duke3d), but others (like Warcraft) just hang.  I
have spoken briefly with Charles Sandmann about it, and he said one
problem was that when the dos/4gw programs hit a hardware interrupt in
real mode they hadn't locked their hardware/mouse handler.  I have of
course tried cwsdpmi with virtual memory disabled, but it made no
difference (does cwsdpmi check that handler memory is locked when a
hardware interrupt occurs?).

I was hoping someone could suggest a dpmi host that is known to work
with dos/4gw and djgpp programs. Or perhaps some general idea about what
would need to be modified in cwsdpmi to get that to work.
