Hope to see my BT 4.0 mouse REBOOT issue resolved in next BT software release.
Update: I paired the same LE mouse (HP Z8000) on a windows 8.1 laptop and there are no issues. This other laptop uses an Intel 7260 AC WiFi/BT combination card with Intel Generic BT and WiFi Drivers. In this windows 8.1 laptop I am not getting reboot/disconnect issues.
