Humm. Yes, I see. I think I have heard of this before, but
it doesn't act this way in the Windows version I am using (6.03).
Hard to say if it is an IDL version problem or a Windows/X Windows
problem. I wonder if you could pass null string values to
the combobox when you initialize it so that it gets set to some
reasonable size initially? As you added items, you could delete
blank items. Ugly, though, even if it worked. :-(
Cheers,
David
