Accordion Menu visual problem in Google Chrome

[NormanRouxel]

1) Script Title: Accordion Menu

2) Script URL (on DD): http://www.dynamicdrive.com/dynamici...enu-glossy.htm

3) Describe problem:

Using the above demo on Google Chrome (currently v12.0.742.122).
If you repeatedly click on the first "CSS Examples" entry so the menu expands / contracts several times, the [+] / [-] icons on the other entries (e.g. on CSS Drive) slowly migrate down and eventually disappear from view.

I don't see this problem in other browsers. Of course, it may be a bug in Chrome, rather than Accordion.
