Site Problems?

[swestrup]

Could a fellow firefox user check something out for me? At http://www.microbytes.com, on the left-hand side of the main screen is a selection labelled 'system designer' Clicking on it brings up a menu. For me, none of those menu items do anything at all, but the same page works fine under Internet Explorer. Is is the fault of the page, or is there something borked in my copy of firefox?

Addendum: Thanks for all the help! Its fixed now, as I posted here.
