Cool - thanks.
Adding the lock messages made this script OK - all the rectangles appear at 
the same time; but the clean-up script that deletes all these graphics when 
I'm done with them is problematic, even with lock screen and lock messages. 
Suspending the dev tools makes it faster - but it still does the rectangles 
one at a time.

But even with this improvement, it's un-usably slow.

I'll go play with painted graphics and see what they do ... I'd be grateful 
for any pointers to sample scripts that use painted graphics (or other 
graphic-intensive examples)
