Odd mac only flashplayer issue


I’m building a AS3 carousel using the code from this tutorial on FlashMyMind:


I’ve noticed that when I view the carousel on a mac and put the browser in the background (by clicking the desktop for instance) the carousel spins at an alarming speed (this stops if you click back on the browser). This does not happen with Windows browsers.

Does anyone know what would cause this? Why just on macs? Any idea how to prevent it?

I’d happy to post any of the relevant code here if it would help.

Thanks in advance for any advice.
