Ok, I've had my mouse for about a month now and the batteries ran out today, so I turned off the mosue and replaced the batteries. Turned it back on, opened the cover, the light was working, looked ok. Went to set it up with my BT manager and it connected fine. But everytime the connection is made, the red LED light goes out (even when I move the mouse). When I open and shut the cover, it comes back on but then the connection is lost. It's a vicious cycle, really. I've tried connecting it again, removing the batteries and putting them back in, turning it off/on, clicking the mouse, restarting the computer and no luck. Any idea what's wrong? Thanks!!! EDIT: I've also noticed that the mouse clicks and works, I just can't move it. So, if I use the trackpad to position the cursor over a link, the dock, etc. and click the BT mouse, it will work (open the program, etc.). I just can't use the mouse to move the cursor.
