I'm currently playing with IDL and trying to persuade my department to
purchase a copy. It doesn't seem to want to maintain its images in X
Windows. The charts go to the graphics window initially, but they wiull
never be updated, even to the point that if the window is minimised when
you plot initially the chart will not appear when you maximise.
Is this a problem with the demo mode (IDL 5.1 BTW), in which case I think
its bringing cripple-ware to a whole new level, or can I expect it to
persist even if we invest in the package.
TIA
Steven

Steven,
I don't think you've encountered a limitation of the demo version; it's
just the way the PLOT command works. For example, if you type
IDL> plot, indgen(10)
and then change the window size, PLOT does not know that the window size
changed. To get this functionality, you have a few options:
(2) Download http://www.dfanning.com/programs/xwindow.pro and try this:
IDL> xwindow, 'plot', indgen(10)
(1) Try the Insight application that comes with IDL by typing the
following at the command line:
IDL> insight
Cheers,
Liam.

Steven,
You should issue a device command before opening a window
device, retain=2
This will allow a backing store to occur and should solve your problem.
