Trouble with graphics display in OS X

P. S. to my earlier message.

I found that I can speed this program considerably by eliminating all 
Lock and Unlock Screens. They are not really necessary in this 
example.

A better example is:

In the message box: go url 
"http://home.infostations.net/jhurley/ControlTurtles.rev"

In this example there are no unlock screens. Unless you put them in 
(inserting unlock screen or wait 0 millisec) the objects move 
abruptly between a few random positions.

If you do insert the forced screen refresh, things slow down 
considerably--much slower than OS 9 or Windows.
