Sometimes I leave my PC doing other stuff while running an upgrade or downloading big files, Syncing my Dropbox, or something like that. After 10mins or so, my screen is locked (which I like).

I just wanted to know if running processes or the Internet connection will be locked too when that happens. Because I don't want to do that stuff after I get back on my PC again.

And if that's the case (halted processes), Is there a way to keep processes / connection running while the screen is locked?
