WordPress is reinterpreting <object> code

I’m trying some Flash photo galleries and having fits. I paste code into a new page, save it, and it gets changed!

Here’s the code I’m TRYING to install:

<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
 codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0"
 WIDTH="400" HEIGHT="370" id="photos" ALIGN="left">
 <PARAM NAME=movie VALUE="http://www.troop-two.org/pics/photos.swf"> <PARAM NAME=menu VALUE=false> <PARAM NAME=quality VALUE=high> <PARAM NAME=bgcolor VALUE=#FFFFFF> <EMBED src="http://www.troop-two.org/photos.swf" menu=false quality=high bgcolor=#FFFFFF  WIDTH="400" HEIGHT="370" NAME="photos" ALIGN=""
 TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/go/getflashplayer"></EMBED>
</OBJECT>

And here’s what is saved:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
<param name="_cx" value="5080"></param>
<param name="_cy" value="5080"></param>
<param name="FlashVars"></param>
<param name="Movie" value="http://www.troop-two.org/pics/photos.swf"></param>
<param name="Src" value="http://www.troop-two.org/pics/photos.swf"></param>
<param name="WMode" value="Window"></param>
<param name="Play" value="-1"></param>
<param name="Loop" value="-1"></param>
<param name="Quality" value="High"></param>
<param name="SAlign"></param>
<param name="Menu" value="0"></param>
<param name="Base"></param>
<param name="AllowScriptAccess"></param>
<param name="Scale" value="ShowAll"></param>
<param name="DeviceFont" value="0"></param>
<param name="EmbedMovie" value="0"></param>
<param name="BGColor" value="FFFFFF"></param>
<param name="SWRemote"></param>
<param name="MovieData"></param>
<param name="SeamlessTabbing" value="1"></param>
<param name="Profile" value="0"></param>
<param name="ProfileAddress"></param>
<param name="ProfilePort" value="0"></param>
<param name="AllowNetworking" value="all"></param>
<param name="AllowFullScreen" value="false"></param></object></p>

Why would it do that??
