To create the iTool system as a singleton object
requires a LOT of infrastructure. That's what you
are seeing here. There is a clean-up procedure
that has to be called when the system exits (it
doesn't when you just exit one of its tools),
but a 20 minute search for it didn't turn up its
name. (But I *have* seen it before, and it *does*
clean all this stuff up! No mention of it in the
documentation as far as I know.)

I find this, too, whenever I import an IDL graphics model
as the "IDL graphics object". Works fine with more atomic
objects like surfaces and the like. I presumed it was a
bug, but haven't ruled out that it is something I am
doing. I do note that the same model works perfectly
in XObjView, so I lean toward the bug explanation.
Cheers,
David
