i just tried this in IE7 and FF 2 against LS 3.1 and was able to add to favorites.i previewed the component directly from content center clicking preview on the component it self.have you tried using firebug or the IE debugger?
The dropdown window doesn't display when it perceives there's not enough real estate. I tried it and noticed when viewing in Component->Edit->Preview that if my component size was too small, the it did nothing on mouseover. The size of the popup depends on what options you've configured, but 260x200 was sufficient for the defaults.Is that what's happening for you?
I don't think it has anything to do with the size of the component as it displays fine when I preview the component itself. It's only when I place it on a page that it hangs and never actually loads.
