I have a .swf file uploaded to http://growitsmart.com/Welcome/Home.html and it works fine in firefox, but when I look at it in internet explorer it looks messed up. You won't be able to see the embedded file if you look in the source code, so here is how it looks. <object classid="clsid:D27CDB6E-AE6D-11CF-96B8-444553540000" id="obj1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" border="0" width="650" height="450"><param name="movie" value="http://www.growitsmart.com/Grows.swf"><param name="quality" value="High"><embed src="http://www.growitsmart.com/Grows.swf" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" name="obj1" width="280" height="190" "></object> HTML: (nevermind fixed) where it says width="650" height="450", I had to change it to width="280" height="190"
Use SWFObject, it can solve many problems referring to web browser. Here is the example to use SWFObject: http://playerdiy.com/support/tutorial/customize-flash-video-player.html
