By the way, when I did that thing Chris_ suggested, a new icon showed up on the tool-bar here.
It's green, shaped like a left-pointing arrowhead, and says "NVIDIA" on it. I have no idea what it is, and as I like having an empty computer, is it something I can get rid of, with no repercussions?
<<<sorry for the silly questions, but you know, this damned cold.....
