Revolution much slower then Hypercard

I don't know if there is any way to change this, but it seems the fastest Revolution will "click" is about 4 times a second (on my computer). This is true even if it isn't doing anything -- not painting, messages locked, just clicking on the card.

The following, on the other hand, runs in about 15 ticks, or a quarter of a second. Obviously it could be further optimized and also needs to be customized to your purpose.

on mouseUp
  lock messages
  lock screen
  put 300 into XX
  put 300 into YY
  put 200 into RR
  put -((pi/2)-(pi/584)) into Rad
  set the style of the templateGraphic to "oval"
  repeat until Rad>=1.5*pi or the optionKey is "down"
    put XX+round(RR*cos (Rad)) into tX
    put YY+round(RR*sin (Rad)) into tY
    set the rect of the templateGraphic to tX-2,tY-2,tX+2,tY+2
    create graphic
    add (2*pi)/584 to Rad
  end repeat
end mouseUp

If you really need paint graphics, then execute the above script and then take a screen shot. (you can do that within Revolution)

Note that this script creates a large number of graphics. Selecting and deleting them by hand will be very slow. A script that deletes them all with the screen locked would be much faster. You can make this easier by giving them all the same name in the "create graphic" step.
