That is a relief. Any others with this observation -- that it works OK 
on a Mac?

Ah, yes. That's because the moveTo commands are being queued every 100 
ms, each with a 100 ms time-frame, and they are queued, so the following 
applet can get behind. I've added a ! ahead of the moveto command. What 
this does is replace any pending moveTo with a new one. I think that's 
the proper behavior, anyway. In this way you shouldn't be able to get 
more than 100 ms behind at any time.
