Page Shadow

[gsthunder]

I tried a search but did not come up with an answer so I am posting here. I am actually making a site that uses a background image on the pasteboard that will carry over and mimic the background image on the actual page. Unfortunately, my actual page has a shadow on the right side of it that I can not make go away and it shows when previewed/published( in the white area anyway ). Is there some way to get rid of that shadow? Never been an issue for me before but it is here.

Thanks.

PS - almost forgot WD10

EDIT - I opened a new 960 webpage, resized it, copied and pasted my content into it, and the shadow is not there? No idea where it came from? If anyone knows why/how it happened and how to get rid of it for future reference I would appreciate it.
