Wordpress Chat IE 7 and page post

Hello,

Running Buddypress MU with BlogMU Theme.

I just installed the wordpress chat plugin from here. Just a couple of things that I am having trouble with.

Is it supported for IE 7? (I installed it and I could not click on the lower right corner, it would show up but not click) Now using opera, it worked.

I am trying to add it to a page, and I don't see the option to add it in my editor.

I think I installed the plugin right, I know I had trouble first trying to figure out the plugins, but I have a few in there that work.

Thanks
