Stop Edit Live from removing Conditional block

We have some conditional code like this:

<p><!–[if!IE]><!–><object tabindex=“0” id=“widgetID” data=“” 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=“,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?
