Bluetooth manager breaks it.

[William John Murray]

  Hello guys,
              I have been using bluetooth to transfer files to and from
my phone happily - thank you.
   I always have a 'Ready for Bluetooth file transfers' icon in my
notifcation area. 
   Suddenly there appeared a blue button with a bluetooth symbol on it,
'Bluetooth manager' I didn't mean to install it. But there it is.

   If I bring up the preferences dialog it looks potentially useful.
But if I change any settings, even if I thn put them back, my phone will
not connect again until I reboot!
I see messages 

"srvc not available"
or the 'seeking' never finds.
     Is there some debug I could provide? Thoughts anyone?
           Bill
