Lotus Notes 8 Integrated Sametime not responding

HiI have Windows XP and installed Lotus Notes 8.0.1. The integrated sametime plug in is not responding.

This is the situation. When Lotus Notes first starts, integrated sametime starts fine. Connects to the messaging community server, loads all the contacts very well. But when I try to double click on a contact to invoke the chat window, it freezes. I have to Kill Notes and restart notes again. The same error with sametime occurs every time.

It was working very well last Friday. I am not sure what I installed in the meantime.

Subject: RE: Sametime integrated client

Does it freeze or just not open a chat window? Often after starting my client, I am not able to start chats. I have to log out of the Sametime community and then log back in.
