I have .WMV files embedded in my web page using media player.

They play fine , but the media player window shifts around the screen (up and down)when you use the scroll bar in I.E, a blank area the size of the player window remains and sometimes obscures other text or graphics on the page. If you click play it sorts itself out , but i have not seen this on other embeded video files? It doesn't do this in Mozzila , only IE?

what is causing this?

can i fix it?

any help appreciated :)
