This the error I get: Microsoft JScript runtime error: Sys.ArgumentException: The format string is invalid.

I get this error when I use the Ext.form.HtmlEditor component along with the microsoft ajax framework.

// Name: MicrosoftAjax.debug.js

I know the error occurs initializing the component and it happens inside a microsoft function but it only happens with this component.


Heeeeelp!
