Has anyone had this issue? It occurs both at work and home, with IE7 and Firefox 2...nine times out of ten, when I try to use the dropdown menu's (to go to the advanced search, subscribe to a thread, etc.), it does nothing. I figured out a way around the search - type some babble and it'll bring me to the search window, but in general, this is a huge annoyance since it's the only way to access the given actions.
