I bought the Wedge Touch Mouse and Keyboard when I got my Surface Pro 128. Both items worked flawlessly until the update for Win 8.1 preview was released. Since then, both the mouse and keyboard are recognized as connected in the Bluetooth section, but the keyboard takes a looooooong time to start working. Then both the mouse and keyboard work fine until it goes to sleep. Then I have no mouse. I have to delete it and pair it again before it will work. I wiped everything and started over from scratch, and everything worked just fine again. I reinstalled 8.1 preview, all good. Then I had to do the update before installing 8.1 and the problem came back again. I thought that maybe it would iron itself out once I installed 8.1 Pro, but no good. Something in the update for 8.1 preview that carried over to the full version changed something in the Bluetooth on my Surface. I desperately need to get this resolved, as I hook my Surface up to a large screen and use the Wedge keyboard and mouse nearly 100% of the time. Thank you to anyone that can point me toward a solution.
