Help with Javascript error in event handler slowing animation down.

Hi all--

I did an animated book cover for my publisher, Baen Books, but an error keeps coming up in my animation.  The actual animating can be viewed here:

As you can see, when the error pops up, the animation grinds to a halt, an it has to recover.  I am not well enough versed in javascript to know what is going on. The error code below repeats over and over again as it plays.
