Caps Lock Error

Any time I apply any effect to a layer in After Effects, I get the message "Refresh disabled (Release Caps Lock to refresh view)". My caps lock key is disabled. I can get the message to go away by double pressing the caps key, but any time I do anything, even something as simple as moving the playhead, the message comes back. I have tried restarting AE and updating to the most recent version, which still did not solve the problem. This makes it practically impossible to get any work done. I am using the built-in keyboard on a 13" mid-2012 MacBook Pro.
