Keyboard and Mouse Unresponsive - Mavericks
Every few minutes, a lot of times when switching to Safari or Mail, but sometimes just while using them, my keyboard and mouse will become unusable. Mouse won't move or click, keyboard won't work at all. Keyboard is USB, mouse is bluetooth. I removed all non-Apple Safari plugins, no change.
