I got an iMac in February and it came with this wonderful little device. After getting the Magic Mouse configured to my liking I thought to myself, "Wow, this is so much better than my old mouse, I will never ever go back!" And yet, here I am using a 6 yo Logitech mouse that has yet to fail me. 90% of the time, the mouse works great, but that other 10% drives me crazy. For example, today I used the mouse all day as I worked with no problems. But 30 minutes ago the scroll function stopped working. I went into system prefs and made sure the "scroll" function was checked, it was. I unchecked it and re-checked it to see if it would reset itself. This caused system preferences to freeze and then crash. I opened it back up, tried the same thing, and it crashed again. After a little investigating I noticed that ALL the touch features had stopped working, not just scroll. Ok, what next? I go to the bluetooth pref pane and try to disconnect the mouse so I can reconnect it and hope it resets. When I click "disconnect", nothing happens. It still says its connected. I try again, nothing happens. So I'm like, ok screw it I'll just turn off the mouse. Guess what? Bluetooth prefs still says its connected. Even closed system prefs and checked it again, still connected. I then turn OFF bluetooth on the iMac, turn it back on, and guess what? The mouse is still connected (mouse is off). So I turn the mouse back on and can't get it to work (read 'connect') at all. Note this has happened several times over the past couple months. I even took out the batteries, logged out and logged back in and bluetooth said the mouse was still connected, wtf? Now I know from experiences over the past couple months that a restart will most likely fix the mouse. But I have a lot of open projects that I really don't want to close, not to mention that I shouldn't have to restart to get the mouse to work (its one of the most important and basic computer peripherals). I like this mouse when its working, but its glitchy operation is really causing me some headaches. This has happened several times now and I'm almost to the point of saying screw it and go get a new Logitech (any recommendations?). Is there something I'm missing here? Its not good when the mouse functions just stop working the middle of an important work shift and you have to close everything via the keyboard and restart to fix it.
