I was bored, so I left SwiftSwitch on for a few days to see how long the timer went on. I guessed that it went to 100 then reset because it couldn't handle 3-digit numbers. Unfortunately, it only got to 60 Hours, then I got this message:
When I clicked 'OK', the timer went back to 00:00:00, but wasn't counting! When I restarted SS though, it worked.
