I just installed a normal MS BT mouse this afternoon.

It did take me some time to figure out how to get the power to the BT adapter in the Sony notebook turned on. I had turned off a bunch of the system tray apps, including the SmartWi thing that let's you manage what happens when you enable the wireless switch.

Fortunately, it works fine with no additional drivers, just using the basic mouse driver, but it's just your basic optical wheel bt-enabled travel mouse. I guess that presentation mouse has extra controls on it, and you need the driver to be able to use the extra controls?
