Not that I'm looking for some sort of "reviving your old dead thread"
necromancy award... but today I accidentally hit the "edit" menu, and
cringed while I waited for my IDL session to crash... but shockingly
it *didn't* this time. At first I thought that some java update might
have fixed the problem... but clicking around I've noticed that some
*but not all* of the buttons on the menu bar actually cause this crash
(or, at least, at this point in time because I'd never thoroughly
checked before).

Causes the crash:
Apple logo
IDL Workbench
File
Navigate
Search
Window
Help

Does not cause a crash:
Edit
Source
Project
Run

I find myself strangely fascinated by this - mostly that clicking on
the Apple logo also falls into the "causes the crash" category, given
that I always that that was an OS-handled button, not an application-
handled button.
