iRite textbox shows unwanted objects

when I use iRite (v 1.0.3) , inside the text box shows 2 strange objects. when I save data into database I saw them stored as ;

<input type="hidden" id="gwProxy"><!--Session data--></input><input type="hidden" id="jsProxy" onclick="jsCall();" />
<div id="refHTML">&nbsp;</div>

when I call them data into (edit data form) a iRite text box that previous objects get from stored data and also another 2 of them shows when iRite loads. in this forum I didnt see any feauture to attache image(screen shot) . this is Urgent matter with my clients site.

Why is these objects, and how can i avoid them?

I ran into this problem a little while ago as well, I found the following post on the FCKEditor forums:

  That's usually some extension that it's misbehaving, so the debugging procedure is to start Firefox in safe mode and verify that it works correctly. Then start enabling the extensions one by one until you find out the culprit.  

in my case, it was The Browser Highlighter add on that was causing the problem:
