I would suspect the Dicom object first. But this could
be (since I know you are writing a log of object code)
that ghost pointer Pavel was going on about last week.
He was telling me to today that RSI confirmed that as
a bug that should be corrected in IDL 5.4, due out
very soon now.
Good luck tracking this down.
Cheers,
David
