This was originally sent to comp.sgi.admin/bugs.
I post it here as well - maybe some other
IDL users have experienced similar things.

Additional info: The IDL session uses a moving window display,
(compound widget by me) wher I store images of up to
500x20000 rgb pixels. (~ 30 MB). But still, when the
IDL session dies, X should free this memory - right ?
