I left my computer, with WinXP, SP3, on and unattended for over two hours, three times in the past two weeks, and when I came back the screen saver which kicks in after 100 min was running. Normally, if I move the mouse, the desktop shows up, but not these times. It does not seem dangerous, but it has never happened before, to see a blue screen, divided in two parts. The right with my login name, and it was saying, one open program (when I click on that, y desktop shows up). The left side gave me the option to change the login to another name, and, finally, on the bottom left, the option to shutdown. A friend told me that it is not a normal situation.
I know that some people leave the computer on all day. So, someone may know if what I see is normal.
This situation has not occurred in the past, but I have not seen the screen saver kick in, all that much.
what do you think?
