Bluetooth Keyboard Continually Disconnects and Reconnects
iMac BT keyboard continually disconnects and reconnects in the middle of typing. Battery level is insignificant (happens when it's fully charged as well as low).
OS X 10.10.4
This began to happen a couple of updates ago - 10.10.3, if I recall correctly.
