Error when changing online availability status

Hello,

I hope, someone can help me. I have a problem with real-time collaboration.

When I'm in a collaboration room (team room), page team members, I change my online avialability status.

Then I get just a blank screen, no error-message. After a few minutes appears a browser-popup with the message that a script is runnig that doesn't come to an end and the question, if it should be terminated or not.

Does anybody know this problem? We are using SAP EP 7.0 SP08.

Kind regards,

Michael
