If you want your Flash movie to remain a constant size and still have it appear as though it is floating in the browser window, embed the flash movie in a CSS container like this:
make sure that you set the box rules of the CSS container like this:
height: 600px;
width: 800px;
margin-top: 0px;
margin-right: auto;
margin-bottom: 0px;
margin-left: auto;
the code around your embeded flash file should look like this:
<div class="flashContainer"><object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,29,0" width="800" height="600">
<param name="movie" value="An_UFO_v-Safak_De-11063.swf">
<param name=quality value=high>
<embed src="An_UFO_v-Safak_De-11063.swf" width="800" height="600" quality=high pluginspage="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash"></embed>
</object>
</div>
