I have a win 8.1 Istick. On powering up, the bluetooth mouse works almost imediatelly, but the Zag keyboard does not - even when its bluetooth connect button is pressed and the led flashes. So I cannot log on. If I connect a usb keyboard I can then log on. If I then go into the bluetooth setup, Zag is listed but wont connect. If I remove zag, and add it back in, then do the code entry thing zag is paired and all is well. Previously this was all unnecessary, the zag and mouse both came up automatically after a restart.

Any idea what changed and how to fix it please?
