Hi!5.1

I am using IDL 4.01 running in a SunSparc (Sun OS 5.5.1) and exporting
the display to PowerPC (AIX)...

If I plot something and drag a window over the image results that the
image is erased! I need draw again the plot to see it...

Thank you for any tip!

You need to set the RETAIN keyword either in a call to DEVICE or in WINDOW.
It would appear that you server does not provide backing store (which is
about what I'd expect of AIX!) so you need RETAIN=2 for IDL to provide a
Pixmap backing store.
