Stop Edit Live from removing Conditional block

We have some conditional code like this:

<!--[if!IE]><!--><object  tabindex="0" id="widgetID"  data="http://www.cdc.gov/cdctv/GetThePicture/CDCtv_Video_Player.swf"  width="500" height="415"  type="application/x-shockwave-flash" title="widgetTitle">.......<!--><![endif]-->     <!--[if IE]><object  tabindex="0" id="widgetID"  classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"  codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0"  width="500" height="415" title="widgetTitle">............

The problem is that the Edit Live editor is removing the conditional block lines. Is there anything we can do prevent this from happening?

thanks
