I have a problem with a Send-Message Hook and EPM.  EPM dies with an 
access violation any time my program has a Send-Message hook set and 
EPM has the "Ring Enabled" option set.  EPM works fine when Rings are 
not enabled.

I have stripped my program down to just installing a Send-Message hook
which returns without doing anyting and this still happens.  In the
full program, both the Send-Message hook and an Input message hook
work fine in every case we've tried except for the EPM problem.


If I run EPM under IPMD, there are 2 threads on the stack when it dies.
The first thread always has ETKE550:2 on the stack and the second thread
usually has 8 or more entries on the stack each at 

	ETKE550:2, ETKE550:4, ETKE550:5, or ETKE550:7.

ETKE550:4 seems to be the most common (more than half the entries).

One time there were only 3 ETKE550:4 entries and the top frame was
DOSCALL1:5.  This is the only time anything other than ETKE550:? has
been on the stack.

Any ideas on why this happens or suggestions for debugging/fixing it?
(We NEED the send-message hook)
