Hello "Bug-hunters @ Skype" =)
I found a big bug in the group call function today.
When I did a call it all working ok, but when anyone of the people in the group disconnects (or hang up). The whole group call ends. And we tried this a cople of times.. Same result everytime..
I think this is a big issue that need to be looked into, because it worked like a swissclock in erlier version of Skype.
Ok, but you might make sure that you don't have a Broadcom Bluetooth process running in the background, even if you're not using it. The very problem you described has been reported to have been caused by Broadcom Bluetooth for other users.
