May be the key that you were trying to add got expired i.e. not available on the server now. Or the key is entered wrongly

Check this link: How do I fix the GPG error "NO_PUBKEY"?

Btw, you can manually delete keys by going into Synaptics.

About mouse. I doubt if it has anything to do with the above error. Check mouse settings in preferences and settings. Something wrong there like pointer speed and acceleration.

Hope this helps.

I will look into that link in a moment. As for the mouse business it got added in there in error, sorry. –  Scott Porter Oct 14 '13 at 23:31
    
I did not get anywhere, but I had fun reading and rerunning things. I sent a request to the dev by way of one of his forums and included a listing of my latest output. –  Scott Porter Oct 15 '13 at 1:05
