Hello, it's the oldest forums member,......or am I? When I leave my PC on, unattended for an extended time, say, for a lengthy download, I come back to a black screen. When I move the mouse or hit a key, a notice is there saying something like;- " This computer is active & locked, only an administrator or support group can access this computer" I don't mind telling you, I went straight into panic mode, & sat there fuming, thinking what NOW??? After having a good chew at my nails, & breaking a couple of pencils [not really] I thought, what the hell, & clicked on "OK" & voila!!....I was back on, what was all that about? I keep thinking that one day it will REALLY lock me out! Another query, how do I increase the time I stay on-line? I know it can be done because I had it done for me, I am now on 10 minutes, how can I increase this, & is it advisable to do so?
