Targus Bluetooth Not Connecting.

Model number 7005803R Targus Bluetooth Mouse

Connects on windows partition without a problem.

Running OSX Lion it repeatedly says it's being refused by the device. I've tried setting it to "automatically make a passcode", "use 0000", and "use no passcode". None work.

Bluetooth settings on my mac allow for automatic connecting/accepting, e.g. with my phone.

Any ideas? Thanks in advance
