It turns out that the trace window is the worst culprit -- but they all contribute.

So the proposed solution would have to be do hide all of them (on activation) and them show them again (on deactivation).

It looks like two ugly choices:
(1) performance so slow that you won't use it.
(2) having the debugger and its windows coming and going each time you activate / deactivate it.

Truly too bad there's no way to turn off the debugger without closing it.

PEM editor is just a form with a timer, actually, and the performance for any form degrades if you have the trace window open. That can't be helped (and, believe me, we've spent some time trying).
