Hi Friends,

I just installed IDL 8, and it's using 334 MB of memory for the
Workbench, compared to 114 for the IDL 7.1 Workbench. This is causing
some problems for me, since I am forced to run IDL in 32-bit mode to
use my external C functions, and I run out of memory.

I was wondering if anyone else is experiencing this phenomenon, and if
there is any way to reduce memory consumption by the Workbench.

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:

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
