You've hit it on the nose, the DeDicer as it's called doesn't dedice on
window movement, only on "Window to front/to back" movement. To coalesce
those puppies you need to bring a window to the front that covers everything
and then throw it back to the back again. This is something that is supposed
to be better in 1.4 (isn't everything :-)). 

I may not have the mechanics of the problem down exactly but that is the
general area of the bug and it's been discussed on BIX a couple of times
at least.

These opinions are my own and no one elses, but you knew that didn't you.
