Wireless IntelliMouse Explorer 2.0 stopped working one morning

New computer a month ago running 64-bit Win7 Home Premium. Plugged in my existing Microsoft wireless combo (Wireless Natural Multimedia Keyboard, Wireless IntelliMouse Explorer 2.0) which both go through the same USB receiver connected to the computer, and all worked well. Installed latest drivers for both from the Microsoft site, and I'm happy.

Then after a couple of weeks, I wake up the computer from sleeping one morning and the mouse no longer works. Batteries were new, but I tried new ones anyway, but no good. It simply doesn't seem to connect to the USB receiver. The wireless keyboard still works. A wired USB mouse works. But not the wireless mouse, even after re-installing the latest drivers and numerous restarts of the computer.

POTENTIAL CLUE: Numerous times I've tried to force the mouse and receiver to re-connect by clicking the sync buttons on both. No good. But here's the thing... when I click the receiver sync button and the lights start flashing as it tries to find a device, AS SOON as I click the sync button on the mouse, the receiver's lights stop flashing.

In other words, the mouse and receiver seem to be able to talk to each other, but they aren't connecting.

ANSWERS TO OBVIOUS QUESTIONS: Yes, the mouse/keyboard combo still works on my old computer. And yes, the mouse and the receiver are close (16 inches).

Ideas anyone?

Thanks in advance.

Anyone?

Also you could try rolling back the drivers to those that came on the CD and running that under compatibility mode.
