What's Wrong?

I quit using the app for about 8 hours overnight and got the "We have not heard from you..." message in the morning. The mouse behavior was erratic within the app - normal elsewhere. The app was unusable because I couldn't close the message or get to the prompt edit box. I had to delete the app, all support files, reboot and reinstall (twice) to get it working.

What Should Happen?

The message (or some other unknown cause) should not render the app unusable.
