I have a Logitech wireless keyboard connected with the unifying usb thing. Often (not all the time) but I keep getting phantom key presses and the digit 1 appearing out of nowhere.

It's like something is triggering a key press every now and again, sometimes repeatedly. It's driving me nuts and I can't figure out the problem.

The usb receiver is in close promxity to the keyboard, within a 2 metre range.

111111111111111!

They 1 key is defintely not stuck.
