Hi Andrew,
I have experienced a similar problem a while back with some code involving a
large number of loops processing a large image. IDL would exit after a
couple of hours on my win2k system. I never worked out exactly why it would
just stop (I never wanted to wait 4 hours for it to see if it was memory or
resources related), but removing the following two lines from my code fixed
it:
caldat,st+(systime(1,/julian)-st)*100./(50.*((n-1.)*r+i)/r), mon,day,yr,hr,mi
,sec
progressBar->SetLabel, "Completion Time>
"+strtrim(string(hr),2)+":"+strtrim(string(mi),2)

This just put up an estimate of when the code would complete. I *know* the
problem couldn't be in David's progress bar. I'm pretty sure the problem was
in the systime call - I was calling it way too often. I suspect this is a
windows problem, but I don't know...
I also had heaps of problems in win95 a few years back when I was using a
Logitech scroll mouse. After about 15 mins of scrolling in IDL I'd run out
of system resources. Weird.

Cheers,
Peter.
