Access denied in IE7/Drupal 6/FCKeditor 6.x-2.x-dev

Hi people,

I've pinned down a possible bug in IE7. Using latest sources for FCKeditor Drupal module (6.x-2.x-dev), latest FCKeditor from fckeditor.net/download, I've set up this environment:

- Website is accessable from http://www.example.com/
- Static content is accessable from static.example.com/
- In website, I've got a JS script with this line: document.domain = "example.com";

I've attached a PNG image that shows the "Access denied" message, and an illustration where this is happening (in file fckeditor/editor/js/fckeditorcode_ie.js). By the way, all works great in Gecko (FF2).

Is this a bug in IE7? Any suggestions on how to fix this one?

TIA, Noor.
