LoL, why not just use "command-w" to close the windows? you could just push it like 100 times, walk away, and come back after making some delicious sangwhiches
And if you were being serious, that is basicly what happened to me, finder windows were open, a billion, i restart so i can start fresh, and after i reboot they are all popping up again, even in safe mode
man that was a frustrating hour or so the other night
