Good luck coming up with an example program you can send
to ITTVIS. :-)
I have *absolutely* no basis for thinking so, but I wouldn't
be a bit surprised if adding 2-3 more GB of RAM to this
machine didn't solve this problem. Let's just call it
intuition, and experience running the IDL Workbench on
a variety of machines.
Cheers,
David

Thanks, David,
I now have 2GB of RAM, and the problem persists, but I've narrowed it
down. (The ITTVis people are helping me as well.)
It turns out that I can make the Workbench reliably hang when text in
the program window is selected and I attempt to copy/cut/paste with
control-cxv. If it doesn't happen on the first or second copy/paste
then it will happen on the third, fourth, or fifth.
Testing a few things:
1. When starting a clean, fresh Workbench, with none of my usual apps,
the problem goes away.
2. With my old Workbench, and the startup file removed, none of my
usual GUIs launch and the problem also goes away.
3. Bring back the GUIs, and I bring back the hang.
Remember that when it hangs, it's on the Workbench that's frozen. All
of the GUI apps/events are running fine.
M.
