Oh, I understand why they switched *that*. Have you ever
made the mistake of printing a page with a black background?
You can hardly pick the soggy mess up!

No, I was complaining about *always* setting the background
color index to 0 when they switch back, instead of keeping
track of what it was before and switching back to that.
This seems to me to be a simple programming error that has
persisted in IDL almost from the beginning of time.

Cheers,

David
