So a few days ago a weird glitch/bug occurs where when the computer wakes up from sleep and I check the Norton performance tab, it says the computer is "Idle", with my activity lightly-greyed out, even though the computer isn't idle as I'm using it to go on the internet and play games. This never occurred before, but I think it might be when the computer IS idle, and before it goes into sleep mode I move the mouse and wake it the screen up while Norton's doing stuff or something. Again, not sure, but this seems like what caused it today. If I restart the computer it goes away, but I just want to know why Norton's doing this.
