I had a similar issue again, although this was close to the end of the fight. I got the message: You can only attack someone when you have at least 14 energy.
I expect that I had defeated them and had to refresh (due to IE7 bug). The footer was at the top of the page, just under the message. And it happened just before this post. 1 IE 7 window open, several tabs, but only 1 ingame.
