Just a question please. How did this happen?
Vista HOME premium. Computer running normally. Left it running when I went for a meal.(Not sleep mode)
Returned and livened it. The desktop came up with a vertical sidebar, with an alphabetical list of my C Drive folders. which could be dragged sideways to show more of the folders.
No problems. I did s system restore and all was normal.
But it puzzles me as a non expert how this could happen without any input from me.Could you please EXPLAIN what happened?
Has been operating normally ever since.
Cheers
Hmm...I'm not to sure why it would have happened, but I see why you would be concerned.  I would keep an eye on it over the next couple of DAYS to see if anything else strange happens, and maybe take note of what happened and when.  Otherwise, a system restore has been known to clear up a variety of issues, and could very well have resolved this.

I don't think it was anything like a virus, as a virus tends to be more malicious and major than something like this.  It is more likely you hit the wrong key combination, or a program failed to open or close properly.  If you are really concerned, you may WANT to run a virus scan to make sure nothing is HIDING out on your machine.Thanks for the reply. I neglected to add that I had run several virus scans which did not raise anything significant.
Thanks again. Will watch out.
