Please submit a complete report about how this fails with CWSDPMI.  I 
also suggest that you cc: your message to Charles Sandmann 
<sandmann AT clio DOT rice DOT edu>, who is the author of CWSDPMI, because he could 
explain what happens or give you hints about it.

Generally, debugging programs which hook hardware interrupts is tricky,
especially with keyboard handlers, since DJGPP itself hooks the keyboard
interrupt.  But it might be that your program or RHIDE has some subtle
bug, and CWSDPMI is less tolerant to such bugs.
