Hi,
As soon as the page opens in ie7 the following pop-up displays:

A script in this movie is causing Adobe Flash Player 9 to run slowly.  If it continues to run, your computer may become unresponsive.  Do you want to abort the script?  Yes  No.  Yes causes the computer to become unresponsive, No naturally does not show the image...Any suggestions?

I was getting this error too. If you change the effects from random to sequential, this error goes away.
