My type cover for the SP3 appears to have a problem. Everything works fine except I seem to have to left-click twice for anything to happen. Eg clicking on a browser link, it won't open unless I click twice. I hear the physical click sound but nothing happens until I click again. I'm not sure if I've got a fault with the switch on the type cover or whether I've accidentally changed a setting somewhere as it seems strange that it works on the second click and this seems quite consistent! It's a bit annoying, though as I use the touchscreen most of the time I don't find it too bad! Do I need to send it back to Microsoft?
