There's some sort of problem with my computer clock.
My windows screensaver doesnt work. In the Display Panel, the preview of the screen saver works fine. But after leaving it for a while (up to a day at times!) I come back and the screen saver hasn't activated.
Also - I use MSN messenger, and this doesn't put my status to "Away" after five minutes of inactivity as it should do as per the settings.
