Does not work in IE 8 or 9

Zimlet works great in firefox!!

Are there any plans to get this working with IE8 or 9?  i currently use Zimbra 7.1.1 and while using this Zimlet in IE8 or 9 I just get a grey bar accross the screen where the zimlet would normally show.  The grey screen spams the entire screen but has the same height as the zimlet.

I would give 5 stars if it worked in the browser most people use at our company.

Thanks
