Thank you for collecting this information in a nice easy-to-read
format, but unfortunately, this does not fix my problem. The PLOT
command works. XYOUTS works, too. I can create windows with no
problems. It's only the TV procedures that cause a bus error that
rudely dumps me back to my unix shell.
I may be wrong here, but I think that if the DISPLAY variable was not
correct, then I wouldn't be able to create any windows in IDL at all
(but I can). Perhaps I'm mistaken about this.
This problem seems to be isolated to TV and TVSCL commands only. Below
is a snippet from another session that shows the !D structure, a
successful plot command, the device info, and the tv-induced bus
error.
With a new IDL session the TV command does create a new window (#0) so
it seems to successfully connect and send windows to the localhost.
Then IDL pauses, while the CPU usage goes up to 100 % on one CPU, then
finally it dumps me back to the shell.
FYI, I can successfully ssh to my linux box (IDL 6.3) and run the same
commands and send the windows back to my mac just fine.
I guess I have no choice but to upgrade if I want my TVSCL back.
Thanks,
Don
