Select Drop Down Menus overlap column headers

I've noticed that in I.E. select menus that are in the grid cells overlap the main column header when the grid is scrolled down. This doesn't seem to occur in Firefox.

Is there a fix for this? Thanks.

This is a bug in IE. It does this on normal web pages that don't contain AW objects. It seems that the SELECT object in IE has a very high Z-Index and is always visible. it will even cross frames (if I remember correctly). All you can do is make sure that you keep it's width smaller then it's container object.
