thanks for the info.

Is this with RC2 or an earlier release?

Could you sample Remote Buddy when you see the spinning beachball? 
(Open Activity Monitor, select Remote Buddy, choose "Analyze" from 
the menu, copy and paste the output either here or in a mail to 
info@this domain)

Is there anything specific you have to do in order for this to 
happen? Or could you give me a set of step by step instructions on 
how you can reproduce the problem?

Thanks in advance!

Best regards, 
Felix
