I solved the problem of the css colors on the module pane (left)
The problem is indeed the right pane. I think it's caused due to the fact I use flash videos on my page. On page Load it wil calculate the spanning of the content pane and the flash videos aren't loaded yet. When the are loaded they will expand and the content will overflow.
I will send you a pm (I will create a tempory super admin account)
Would love to see another game tempelate
