Well, it either locks the SIQ or traps on me, even with known good
programs.  It even locks the SIQ if the slave program is multithreaded and
I'm working with a non-message queue thread.  Go figure.

If you have two monitors.  Otherwise, you'll never be able to see what you're doing.

I can't believe that I can't switch away from a full screen debugg session
while single steping a window procedure because the system will hang.  No
wonder PM programs tend to have more bugs in them than VIO ones - the
debuggers aren't worth a %^&*.

It looks like I'll just have to get FP17 to fix the SIQ problem and get
into the habit of not running much else while debugging. Sheesh.  This is
just like running Windows.

Thanks anyway.
