IDL had that capability at least since 6.x, where too many recursive
function calls would bring down the whole linux system.

I always thought you were psychic, Paul!
No, I didn't hear from any other Windows users, and
yes it did turn out to be my COMPUTER'S problem and
NOT IDL's!
The clue came when I finally heard back from technical
support late this afternoon. They had been unable to
duplicate the problem on their computers and they suggested
a couple of things about cleaning up the workspace (deleting
some files that accumulate, etc.). This I did. Then, at
their suggestion (I am too old, apparently, to remember that
I used to suggest this to EVERYONE who had object graphics
problems!) I ran the program with software rendering turned
on and the program worked correctly.
OK! So I immediately downloaded the latest driver for my
NVIDA Quadro FX 580 graphics card. That took about 20 minutes
(big!) and my desktop is a total mess now, but in fact, I just
ran the program and it works properly with hardware rendering!
So, mea culpa! This problem solved. Now, I can *really* get
back to trying to make these things work properly. :-)
I think I just got too sucked into all these reports of
problems and I forgot to take a couple of deep breaths and
THINK about things before I rushed to judgment. Wish I
could say it won't happen again, but that's not the pattern
I see developing in my life. :-(
Cheers,
David

Has anyone else who has a similar setup to you reported the same issue with that colorbar program? (I.e. via email since
no windows folk have responded to the newsgroup)
Otherwise, how do you know it's an IDL problem and not a your-computer problem?
Now don't get me wrong: I think the former is more likely, but you can't rule out the latter without corroboration from
other users. Especially since the effect (basically crashing your entire system) is rather monumental.

Well, maybe things aren't quite this simple. Now
running the 32-bit version of the Workbench, I went
back to Mark's original program he sent this morning.
The first time I ran it, it crapped out at the Colorbar()
line, but produced an error. All seemed to be well.
I could move the cursor, type in the editor window and
at the command line, etc. But nothing else would happen
in the session. I couldn't even get a simple Plot command
to work.
I killed that IDL session and started the 32-bit version again.
This time when I ran the program, IDL crashed with a fatal
error, but it didn't bring my entire machine down with
it.
I really don't know what is wrong, but clearly any
more colorbar experiments are going to have to be
put off until IDL 8.2 comes out. This current version
doesn't like me at ALL!
I wrote an article this morning asking the question
"Is IDL 8.1 Useable?" I didn't honestly know the answer
when I started the article. But I think after today's
experience the answer for me, anyway, is "No, not at
all!" At least not if I intend in any way to use
the function graphics routines.
Cheers,
David

OK, I went into my Users/David/.idl folder and deleted
the itt folder I found there. This allowed me to start
up the 32-bit version of the Workstation. Running this
version, and the ContourPlotCrash program, I was able
to run to completion and see the aesthetic mess you
are talking about!
I guess we are making progress, if running crippled
software is progress. :-)
At least now I might be able to get back to my
original task, which was to make a filled contour
plot with a limited number of colors and a
corresponding color bar. Alas, from everything I've
learned in the past couple of days, I don't think
this simple plot is possible in function graphics,
but I'll press on anyway.
Cheers,
David

It produced a yucky looking plot with the colorbar labels all smushed together, but it worked. No crashes or hesitations.
I ran it as a program, and also pasting each statement on the command line. Worked both ways.

Program ran, window and plot were created, nothing else happened. No crashes.
Using IDL 8.1 (command line) under OS X 10.6.8 on a Macbook Pro (15", 2.53 GHz Intel Core i5, Built-in Intel HD graphics and PCIe NVIDIA GeForce GT 330M).
The colorbar labels *do* look horrific (four trailing zeros after the last significant digit), but not enough to make my brain crash.
