Page won't center in IE

[richtestani]

On the following page.
I can't seem to figure out why IE wont center my div in this cell.

http://www.divvies.com/pub/

Of course Moz and other browsers work no prob.

Any help on this is appreciated.
Thanks

Works for me in IE 6

I should have not said the page is not centered, but the <div> in the cell isn't.

#mainbody centers in Moz and others, but not in IE 6.

If you compare in the 2 browsers, you will see.
Thanks

Still works for me. Really, everything looks exactly the same and appears to be working ok. I'm on Win2k using IE6.
