Ouch!

Another thing I have noticed (I just saw it with this
example). If I make a typing mistake with new graphics
routines (in this case, I just cut and pasted without
accounting for the long line breaks), then fix the
problem and run the code again, either by pasting to
the command line or by running a main IDL program, I'm
pretty sure I am crashing IDL about 50% of the time.

In any case, this is the most fragile version of IDL
I have ever worked on. I know it has crashed at least
5-6 times in the past three days. :-(

I have the impression it is always when working with
objects, but I can't be sure about that.

Cheers,

David
