Keyboard Setup Assistant KEEPS POPPING UP!

In the last week or so, The Keyboard Setup Assistant keeps popping up and telling me that "Your keyboard cannot be identified and will not be usable until it is identified. If your keyboard is working properly and you have an additional USB input device connected to your computer that is not a keyboard, you can skip this step.

The only option is to close the window or hit "continue". If you hit continue, they ask you to press the button to the right of the **** key.

I have a macbook and a bluetooth wireless keyboard that I use and have been using and it works fine. I don't need to set up anything, but this window keeps coming up over and over. Any ideas? I've re-started, updated software, restarted bluetooth. I can't think of anything else.

Thanks
