We have seen this exact same problem since going to DEC-MOTIF v1.2-3.
The IDL window absolutely does not become active, therefore the private
colormap never comes into play.
This is really becomes a problem with 24-bit graphics engines.
I have an ALPHA running v1.2 of DECW-MOTIF and it behaves as it should.
I therefore have to say something changed in the X11 server in the way
it interacts with IDL.
One of my users displays his images within widgets. THis appears to work
but you should not have to this. I'm glad someone else has finally seen
this problem other than us.
If you don't have to upgrade your DEC-MOTIF, DON'T!! 'til DIGITAL or the
IDL folks have an answer.
