Yes, the name reset is also something i've noticed myself. With all the bluetooth issues going on on the Ativ, that might also be a reason why it's difficult to get a descent connection using bluetooth.
It's almost like some values aren't written to the registry or configuration file in a permanent place. These settings should be permanent, but aren't written to the right place so they are lost after a reboot. Possibly a rights issue somewhere, be it registry or file system. I'm also wondering why only we seem to be having these issues, since i doubt these 'settings not being stored permanently' are just driver related. Seems funny to me that i.e. Nokia users arent reporting having these issues.
