RTE - Loading Editor

Hi there,

I have RTE version = "2.0 beta 2" installed on my site. Lately I am getting notifications from my IE users that they cannot edit their saved text.
I checked the problem myself. While Firefox runs with no issues, IE seems to flip out when getting a more complicated text in the QS1 param. I use this parameter to send the default content to the editor. My IE version is the latest with latest patches on windows profession 2000.
It is actually dying on the line with: frames.message.document.designMode = 'On';

However I know, if the text is simple, it all works fine.

Does anybody know about this issue? Tried to search the forum but no luck.

thanks,
Attila
