body / background overlaping

[Daniel555]

I am using repeat-y for a body image that takes up about 1/8 of my forum width on the left side. My forums are centered with a width of about 1000 The problem i am having is that when i restore or reduce the size of my browser window the background gets on top of the body (the samething happens when i change my screen resolution to a lower one). How can i make it so that the body and background stay right next to eachother instead of overlaping when i change the size of my browser?

The first one shows how its supposed to be, the second shows the problem.

nvm i fixed it by changing the extra css attributes for body.
