Logitech Wireless Mouse Not Being Recognized By MBP

Hi I bought a Logitech wirless mouse that uses Bluetooth to work. I set it up and it was working fine for the first few days and now all of a sudden when I turn it on it doesn't become recognized. The Bluetooth icon at the top right of the screen doesn't change like it usually does. I tried new batteries and that didn't work...I tried re-configuring the mouse and it says, "No mice found. Please try again." It is also in Discoverable mode. So now I don't know what could be wrong. I don't know if it's my mouse or my computer that is messing up. Anybody have any ideas? Thanks.

Hmmm....I just turned Bluetooth off, then turned it back on and now it's working. I shouldn't have to do this everytime though. Anybody know what's wrong?
