Active Menu Stomps Table Header

Hi! I really like active menu, it's a feature I've been wishing was in Drupal for a long time. (I wonder when/if we could see functionality like this in drupal core?)

Anyway, I noticed a problem using it today. Whenever you're on a page with a table, the table header "follows" the top of the browser viewport as you scroll around. However, expanding or collapsing a menu with Active Menu will "crash" this table header, causing the table header to either not appear or not disappear. (Depending on its state before Active Menu was used.)

I've tested, and this problem appears in IE 7 and Firefox 3 on Windows and Linux.

I hope you find time to work on this problem. I'd really hate to see this module bitrot.
