Bluetooth causing System Preferences to hang in Lion?
just put Lion on 2 MacPros at work. on one of the machines, I'm getting a weird hang when connecting to Bluetooth. It'll connect (to my trackpad in this case), work for a few minutes and then stop working. But it also causes System Preferences to hang/crash. I can open SysPrefs but not click on any module. Also I get a beach ball in the menu bar for any Apple sys prefs. First time, i just restarted the comp and when it rebooted i got the "Bluetooth unavailable" icon (greyed out with the wavy line in it). Then I tried trashing the bluetooth prefs and resetting SMC, which allowed me to connect on reboot, but again it crapped out after a few minutes?
Any body else having this issue or had this issue with older OSes? To be honest I hadn't used Bluetooth very recently under Leopard or Snow Leopard, so i don' t know if the issue existed before the upgrade to Lion.
What about tryin gto reseat the Bluetooth antenna
