my forum stretches the page :(

[se_p800]

please go to http://customizepsp.co.uk/forums/index.php?styleid=14 (make sure you have the dark_vb style set) and you can see that the content stretches the page. How can I fix this? I have alredy tried several things.

Thanks

EDIT:

I changed the location of "$spacer_open" (i moved it down a few spaces) that seemed to fix it dramatically, but it still stretches by about 5 pixels!

ALSO..when i view a thread sometimes it can be stretched quite wide for no apparent reason..

Thanks for reading

Please can someone help! Is there anyway to make it so the forum never stretches? Ive tried editing stylevars etc. Here is an image of the problem aswell:

I know this is happening because I added adsense down the side, and I tink it may have just shifted everything to the right..??
