Radtech BT600 freezing Macbook

Hi All-

I have a very frustrating issue I am hopeful that someone can help me with!

First off, I have a 2.16 Intel Core 2 Duo running OS 10.5.2.

I have a Radtech BT 600 bluetooth mouse and EVERY time the batteries are about to die the mouse will freeze and no matter what I do I cannot regain control of the pointer. I can use apple + option + esc to shut the programs down but the only way to regain control of the mouse is to turn off the computer, which can only be done by holding down the power button and restarting the mac.

Every thing else on the computer works the keyboard, clock, programs ect.

Can anyone help?

BT 600 Mouse

Thanks, I have. It came with a cheap set of rechargeable batteries. I bought new ones and an independent charger (the mouse charges batteries too) to no avail. Regardless of what batteries are in it, once it dies, the mouse pointer freezes and thats it. No matter what I do now, power the mouse on / off, change batteries, connect it to the USB, I HAVE to hold the power button down to use the computer again.
