Strange behavior with Zoom and Image control

Question

HELP - I have a strange behavior (bug?) with using Zoom
effect on an Image that has been placed on a Canvas. I am using
dynamically instantiated images which are placed on a canvas inside
a panel. I then assign a Zoom IN and Zoom Out behavior to the
image, triggered by ROLL_OVER and ROLL_OUT effect triggers. THE BUG
is that the image jumps around on the Zoom OUT and lands on a
random place on the canvas instead of coming back to the original
spot. This is especially true if the mouse goes in and out of the
image very quickly. HELP -- what am I doing wrong? Computer = Mac
OS X 10.4.9 Flex 2.0.1
Here's a simple demo of the bug -- be sure to move the mouse
in and out rapidly:

There must be bugs in the Zoom effect code -- I changed the
Zoom to Resize in the above code, and it works perfectly. Of
course, Resize is not as nice as Zoom because you can't set the
resize to be around the center of the image, but at least it works.
Does anyone know about bugs in the Zoom effect?
