1) Script Title: SlashDot Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex1/slashdot.htm

3) Describe problem: When contracting/expanding the menu in IE 7.0, the entire browser window stutters during the animation. This does not occur in Firefox. I've viewed other implementations of SlashDot in IE 7.0 and they don't stutter, so it seems there's a problem with something I've done rather than the browser.

The site that I'm building can be found at:

An example of site that I've found without stuttering is:
