Hi

I just to report a really strange bug nathanael and I encountered 
regardings the refreshing
of the screen on mac. Nathanael implemented a double-buffering for my 
turtle and it worked really well on pc but on mac we got the problem 
that all the widgets were refreshed
  even when they should not have.

We could never identify a reproduceable snippet to submit it to the 
list, this was really vicious
because this was in the middle of the different processes interacting 
so it was extremely plainfull to debug because any change was changing 
the behavior (no halt, no transcript show allowed).

So if somebody see that this is happening. Believe us. We were amazed 
that the same code was not running the same way on mac and pc.
