Well it works fine, and it (almost?) the solution, i.e. it works for
NSBackingStoreBuffered and NSBackingStoreRetained windows. The flashing
reappears for NSBackingStoreNonretained Windows. I didn't have enough time
yet to check against the OPENSTEP 4.2 behavior with such windows and rerun
runloops. Not quite sure when I'll get to it but it won't be too long. (just
not today (or rather tomight)).

I'll keep you posted.
Dave.
