What does this message mean?

I get this message every now and again. I have no idea what it is referring to. I notice no change in my system's capabilites or performance when this message appears. I simply click 'ok' and all seems well.

I do nothing to instagate this. It just happens at random.

What is this about? Ideas?
 
control panel/mouse/cordless/ you can change channel to stop your pc being interefered with by another pc using a similar mouse.
Like in an office for example!
