I'm having a similar problem. It looks like the submit button is getting partly covered up by the <p> tag or the <div> tag above.

It's doing the same thing on the "Post Reply" page

I have got the IE 6.0 version. It looks like it works ok with FireFox. Some users might have the 6.0 version of IE

I would appreciate any suggestions.

Thanks.
