Hi,

I'm quite new to IDL so forgive me if I've got the point to the question
wrong..

I had much trouble with getting colours (ie not greyscale) to work
correctly in runtime versions of .sav files but [thanks to DWF :-)], I
found that if you include "Device Decomposed=0" [oh no, not again! :-) ]
at the beginning of your program and then create a .sav file, you can get
colours to work correctly on any screen mode.

I hope that this helps,

Robert
