Alright, let me explain the little issue. I've been using a Logitech MX1000 for a while and it worked great. Well, last month and now today, I started to get an issue where it was clicking properly. Also, when I put my mouse to the bottom of the screen (where my dock is hidden), it only shows itself when I click down there. The dock also doesn't magnify when the mouse hover over anything. It's kind of frustrating. I've disconnected the mouse and the problem doesn't happen with the touchpad on my MacBook Pro. Every now and then, the mouse kind of lags too. When I switch to the Windows XP side, there is no lag or issue of any sort with the mouse. Any suggestions short of buying a new mouse would be awesome.
