The first few days I ran this it worked perfectly. Recently when I return from the screensaver though, I am getting an error "Script event timed out." While this doesn't seem to be causing any problems as far as crashing the system, or even causing the script to stop functioning, it might cause problems for people who have their systems set to log out or shut down automatically. If it seems to be working fine for everyone else maybe (hopefully) it's just me having this problem.

So far I know it was not related to the "giving up after 30" command as I had suspected previously.

Your Mac has issues. First, the Keychain menu item is buggy, now your own cryptic workaround has started giving you errors.

I think I'll pass on your tips, thanks all the same!
