When I embed a Youtube video or other flash content right below Menu, the popup menu appears behind the flash player on IE 8. How should I fix this? I tried setting z-index on the flash player to -1, doesn't seem to work.
This is not a problem on Firefox 3.6.
Did you embed the Flash object using the wmode=transparent parameter? See for example http://kb2.adobe.com/cps/155/tn_15523.html and http://www.sitepoint.com/forums/printthread.php?t=158317&pp=25&page=4
