Resolution: 1600x900

This is for Username up top, and for the 'Search this forum' feature.

 

It doesn't look bad, does it?

 

It's definitely lower than mine.

 

True, in FF386 it looks higher.

 

I'm on Windows 7 / Firefox 3.6.8 if that matters. 1600x900

 

Google Chrome on Fedora GNU/Linux looks pretty much centered.

 

it's a bit low for my liking on chrome, but that is really low on IE
