4.0.7 upgrade - Login not working...

[Footman]

The upgrade (4.0.6 - 4.0.7) went perfectly, so I thought. The login area in the upper right of my site doesn't work as it used to. Now when I place the cursor in the "username" and "password" fields, the text that's already there doesn't disappear as i always has. Also, if I just back them out and type in the username and password and click login, I get the "wrong username and/or password screen, even with the correct info.

The only way to login is to use the center login box.

Any idea what happened?

This appears to ONLY be happening with my FireFox 3.6.10 Mac version. It all works fine on Safari and Chrome. I do not know about windows versions of the browsers.

Upon further investigation it also seems to be related to how my theme works with FF as it does not happen with vB's default theme. I have the question put in with the theme developer.
