Adesso wireless mouse doesn't work in Mountain Lion.

My Bluetooth Adesso iMouse S100 doesn't work in Mountain Lion. It barely moves and constantly halts as if its driver is continuously interrupted. It is unusable. It worked beautifully in Snow Leopard.

I don't believe the problem is in the mouse, but just for completeness the batteries are full strength. The Bluetooth control panel signal strength for the mouse ranges from -50 to -48, which may be low but I'm pretty sure was the same in Snow Leopard.

Has anyone experienced and have a fix for this problem?

Thanks.
