I did a little testing on your site, and I'm pretty sure that the pushing is actually a result of your tickers.
If you head to "Edit Your Account Profile" and check the box for "Force Simple Layout," you shouldn't get a scrolly anymore. Try shrinking your tickers by like 20 or so pixels, and see if that doesn't fix it.
Odd I'll look at it. I had originally formatted them at 1024x768 but I'll double check it.
Nope still pushes on my laptop at that resolution unless I go all menus on left. As soon as I put a menu on the right hand side and go to the forums page I get a scroll bar.
To clarify...that is with Force Simple layout checked.
