Ken, Thanks for your careful test. This is driving me nuts and I can't find a work-around.
I think the problem is RR not doing a screen refresh after each of the MULTIPLE steps. (I have always, in OS 10) had to do a refresh after EACH step. Would you please try this for me: on mouseUp put 200 into x put 200 into y put 2 into dx put 1 into dy repeat 100 times put x,y & cr after tPoints add dx to x end repeat put 200 into x put 200 into y repeat 200 put x,y & cr after tNewPoints add dy to y end repeat lock moves move button "one" to tNewPoints without waiting move button "two" to tPoints without waiting unlock moves end mouseUp When I tried your script I got what you got: Smooth motion. But with the script above, eliminating possible problems with the graphics, I get herky-jerky motion with the second move. I suspect it is due to the multiple steps in the move. Running RR 4.6.3 and Mac OS 10.6.8 Thanks again, Jim > Jim, I'm not seeing that on my Mac (I'm running Lion if that makes any > difference, and LC 4.6.4).
