Delay of animation on Slide display

[Mark]

Hi all!

I inherited an experiment that draws a circle on the screen and then 
refreshes for a set duration to make it appear to move.  The problem I am 
having with it is that there is a noticeable delay, like 2 seconds, from 
the time the circle appears on the screen and you start moving the 
joystick, until the time the circle starts to move.  Essentially it 
appears, you start moving the joystick, nothing happens for about 2 
seconds, then the circle "jumps" to wherever the joystick coords are at the 
moment and then moves perfectly in time with the joystick motion.

If I could get rid of that lag/delay, there would be no problem.


The inline code that governs the moving circle is below.  The inline object 
follows a slide object in this procedure, which is blank except for a 
SlideImage called 'TheCircleL' which is 5k.  The inline code sets 
TheCircleL's X and Y coords equal to the joystick coords, then redraws the 
slide.

Any help would be greatly appreciated!

blankL.draw
