Re: IDL crashing badly on my solaris 8 system


Well, I had the notion that it might possibly have something
to do with hardware rendering (which I didn't realize was
turned on by default).

Once I figured out how to toggle to sofware rendering
(in IDLDE preferences) BINGO,  it worked beautifully.

So, 2 questions:

1) is there a similar way to turn off hardware rendering
   from the IDL prompt (not in IDLDE mode)?

2) what can I do to get hardware rendering working on this machine?  and is
   it worth it?

OK, that's really 3 questions.

Thanks a bunch.
