No, no elements with absolute position.
Only an updateprogress where an with absolute position is used. But I have the same effect when I exclude that.
There are a lot of DIV tags around my treeviews. In the masterpage and also in content page until the tree is embedded.
So i checked the stylesheet, but I didn't find anything that says \"absolute position\"
I could post the source, but the aspx itself has 500 lines :-\\
