Thanks for replying. I can confirm that after I installed the driver recommend by Acer, bluetooth seemed to work fine. I changed the settings of my pc to never go into sleep mode (like I mentioned before, sleep mode seemed to trigger this 'bug'). Since the time of my previous post, my bluetooth driver has bugged out only once. I had a lot of different .exe files on my pc at the time (all different but similar installation wizards that I downloaded from the Intel or Acer website) and I decided to get red of them all and uninstall the (now greyed out again) bluetooth driver and start out 'clean'.
