I can key in a message. But when I move my cursor to the paper clip icon (or any of the icons in the message toolbar, for that matter) and click, nothing happens. The icon doesn't even highlight to indicate it is responsive to my cursor. I do get a pop-up balloon that identifies the tab, but that's it. I can't do anything with it. Also, when I go to the "Additional Options" section below, I can't access any of the links (i.e. Miscellaneous Options, Attach Files, and Thread Subscription). I'm starting to wonder if this is a browser compatibility issue, though that seems strange, since I use Firefox, which a lot of folks on here use.
