Appreciate your input. Agoracom wrote me back on this - they just said my browser was to blame. It helps when you write in - I'm using Firefox 2.0.0.7 (Agora uses Firefox to test), so the fact that you're using IE7 and seeing problems is a help. Thanks.
I am trying to help Agoracom sort this out, although at some point I give up.
Interesting times on the markets.
