I have also run into this problem whilst using RHIDE, Allegro, CWSDPMI.
Is it possible to use any other DPMI server in DOS?
(using the above combination and preferably a free one). 

In the program I'm currently working on, the debugger locks up as
soon as I get to the timer initialisation part of the progam
during debugging.

It basically rules out using the debugger at all for my program, 
and in the long term this is not really acceptable.

If Robert Höhne believes it could be a problem with RHIDE, I'm
quite happy to email him, (or anyone else who is interested),
a copy of my config from RHIDE.
