I have a scripted solution for OS X. But it is not very good. You can
see this best in Turtle Graphics applied to controls:
In the message box: go url
Just click the button "Fixed/Not fixed for OS X"
The issues are related to the screen refresh in situations in which
there is an evolving graphic, a display generated in a repeat loop,
or mouseMove. One can force a refresh with "Wait 0 millisec" or
Without the forced refresh, things are displayed very quickly but
With the forced refresh things are displayed smoothly but much more
slowly than in OS 9 or Windows.
I would hope there would be a compromise. But maybe not. It may be an
inherent problem with the greater demands that OS X places on
graphics display--as Richard pointed out.
