Link Bar Problem

http://unstoppableforce.forummotion.com/portal.htm

I logged on my site today only to find that my link bar, which usually goes all the way across in one row, which looked really good, is now in two rows, and doesn't look as good. Unless i changed something in my sleep, i didn't mess with anything. I have been trying to figure out how to fix it, but i can't seem to figure it out. Any help here would be hot

Hello,

At the moment, I'm using Firefox 3 at 1024 x 768 resolution and everything is on one row. Extra links may appear once you're signed in, thus pushing links into a second row. If this is the case, try using smaller images for your link bar.

I was able to fix it last night. Somehow it got changed to 80% of the screen, and i changed it to 100% fixing the problem
