iWeb problem

Anyone know how to get around this?

Made a web site for a friend, if you go to the site at www.themarbleshop.info you will notice the tilted M logo at top left has a shadow around the box. When I cut from a word or pages doc the shadow isn't there, paste into iWeb and it's there. Anyone know how to stop this when pasting into iWeb ?

I assume that you've already checked this out, but have you made sure that the shadow option isn't selected in inspector?
