I had no problems with my bluetooth headphones in build 7000, but when i installed RC 7100 the headphones will install and work on initial setup, but after they are turned off they will not reconnect. I have to uninstall them and reinstall them, this is becoming a headache as i use them often. Also, in build 7000 after i turned off the headphones the default playback device would automatically switch to my speakers and then back to the headphones when connected... this does not happen in RC 7100? Any help would be appreciated!
