While my progress bar windows are updating, the BadMatch errors are being thrown in the IDL window. After several hundred of these errors, the entire workbench/ENVI crashes in a glorious fashion. I've followed David's article:

Try replacing this line in progressbar__define.pro:
self.drawID = Widget_Draw(self.tlb, XSize=self.xsize, $
YSize=self.ysize, RETAIN=1)
With these two lines:
retain = (StrUpCase(!Version.OS_Family) EQ 'UNIX') ? 2 : 1
self.drawID = Widget_Draw(self.tlb, XSize=self.xsize, $
YSize=self.ysize, RETAIN=retain)
Does that help?
I should be doing this for all draw widgets (which I actually
do now), but this program is very, very old. :-)
I'll update the program in a second.
Cheers,
David
