Thanks for the pointer. I can see it now.  I think the problem, however,
is that although there is a background in
cached image, the alpha on the color is 1, so when it gets composited
(again) to the drag view, it
gets ignored. What I'm not sure is if that's an error in how we
interpret compositing and alpha values or if it's an error on the
NSColorPanel's part in drawing the image. I'll have to test it out,
unless anyone knows how this works.

Try the latest CVS.  The problem is  that X cursors only work within a
particular window, not globally, as is assumed in OpenStep. I've updated
the cursor handling to account for this, I think.

OK, that's probably what I saw.
