Well, I think David's comment should have been more along the lines of it can
be somewhat difficult (or dangerous perhaps?) to run a debugger on the same
machine as the PM code you are developing, but it's not impossible.  And until
IPMD that debugger had to be a text mode debugger (ie: you couldn't use
Multiscope in PM mode when debugging PM applications), and you had better make
sure not to stop your program at a breakpoint in a message procedure and then
Ctrl-ESC out of the debugger back to the PM screen.  Instant system hang.

This all relates back to the single input queue for applications and since
the debugged application was processing a message (and at a breakpoint),
you couldn't use the keyboard/mouse to switch back to the debugger to
continue the application.

Personally, I've done all of my PM debugging using CodeView (and now IPMD)
on the same machine as the code I was debugging.  I've also hung (and had
to reboot) my machine a good number of times under CodeView when reflex took
over and I Ctrl-ESC'd back to PM while still at a breakpoint.  [It's that,
"start-pressing-the-ke...SH*T!" syndrome :-)  at least CAD still worked]

Anyway - IPMD has different debugging modes (synchronous/asynchronous I
think - I haven't played with them much), that is supposed to take care
of this, allowing you to use the PM debugger to debug PM applications.  I
haven't yet had a chance to use it, but it sounds nice.
