I suspect this is a problem peculiar to the Mac.

When I run:

    set the lockmoves to true
    move grc "Oval" to tPoints without waiting
    move grc "rectangle" to tNewPoints without waiting
    set the lockmoves to false

The oval moves reasonably smoothly, but the rectangle take several abrupt steps.

Is this another manifestation of the screen refresh problem on the Mac? Normally I intersperse a 
"unlock screen" command to force a screen refresh, but I can't do that with the 
"move" command.



I don't really know; but I set up a plain vanilla stack "Mover" with a rectangular graphic and an oval graphic; "rekt" and "oval" respectively; the card containing this script:

on mouseDown
  move grc "rekt" to the mouseLoc without waiting
end mouseDown

on mouseUp
  move grc "rekt" to the mouseLoc without waiting
end mouseUp

all this on a merry old PPC MacMini running 10.4.11

and, frankly didn't notice anything particularly different about the way the
two graphics moved............... this may say something about your Macintosh or
your code.................

if you wish you may download the stack here:

of course one can also have quite a spot of vaguely infantile fun playing around with it.
