Using new Dell Vostro with Windows 7:
I recently downloaded the latest version of FireFox. Prior to that, my system stayed up unless I chose to close it but now, when I'm away for a while the system is reverting back to having me enter the PW. Once the PW is entered I'm taken right back to where I left off.
In other words, the system is not shutting down, it's just recognizing that I'm away and going to this "enter PW" thing before I can get back on line. Is this a Windows thing going on or a FireFox function?
