I have a Microsoft wireless mouse which i use with my Acer tablet. I placed the tablet on my desk in front of my PC (running win7) and when I went to use the mouse with the tablet, it had instead 'synced up' with with my desktop PC. How do I stop this and instead have the wireless mouse work with my tablet as it has been doing without issue? PS - I looked but didn't find anything to turn off on the PC that would stop the wireless mouse from working with it
