Forum Tab key oddness?
 

I recently upgraded from an older 3.6.x installation to the latest 4.2.0 on my forum. Everything is working fine with one exception: I can no longer hit tab from a new thread text box to the "Submit New Thread" button, nor hit tab from the quick reply box.

This is more of a nuisance than it sounds like, because "tab+enter" is my standard behavior for posting on forums and a very hard habit to try to undo.

The thing I don't get is.. this works fine here on vbulletin.com, and we supposedly are using the same version. But when I compared the HTML for sample threads from my site and from here, they were very different in a lot of places, and I don't know why that would be the case.

So I'm rather confused.

I use Firefox as my primary browser and have confirmed with others the issue. The forum is located here.

Thanks for any assistance.
