MW fatals when debugger/POSE quits

[Jason Dawes]

I'm using MW R5.1.1 on NT4.0/SP6 with POSE 3.0a3 and the most recent
plugin.  Every time the debugger/POSE exits, the IDE crashes.  (The Dr
Watson log indicates the problem is occuring in a call to
WaitForMultipleObjects).  Has anyone seen this problem before or know what
could be contributing?
