It's more likely that it happens when you're trying to hit CONTROL-W and APPLE-W, the command keys aren't registering. Could also be that those keys have been weakened on your keyboard. Hell, I know the W command well and I hit it by accident sometimes.

That seems possible as well -- if your CONTROL or APPLE keys are stuck, for example. Have you tried swapping keyboards?
