Internet Explorer Script Error

 From:  Syziph
I recently upgraded to IE7, When I tried to activate the Image button it appears this confirm box.
Internet Explorer Script Error
An error has occured on this page:
Line: 95
Char: 5
Error: 'moi' is undefined
Code: 0
URL: moi://commands/image.htm
If I press 'yes' nothing happens.
Do I have to change the setting of Internet Explorer in order to enable this tool?

P.S.: don't press the link above:)
