Thanks, David. This got the job done. It's ironic that in this day
and age of parallel computing, ITT-VIS chose to merge two processes
together.

Yes, this is the result of combining the Workbench and the IDL
process together, something that was done in IDL 8 to make
the Macintosh version work properly:
http://www.dfanning.com/misc_tips/idl8mem.html
It is causing problems for other versions, but especially
for Windows users. There is some talk of separating the
processes again for Windows machines in future versions
of IDL, if not to reclaim memory, then to make the Windows
version stable enough to use. There seem to be some especially
bad interactions with JAVA. :-(
Cheers,
David
