Desktop icons will not stay at set size

[FClifton]

Not sure how I did this, but I have gotten into a state where my desktop
icons will not stay at the size I set. If I set them to classic size, the get
small, but then they grow back to giant size. If I go back to View, large
icons are again selected even though I had selected classic. If I use the
CTRL + mouse scroll wheel, every turn of the wheel makes them smaller but
they immediately grow large again. This started when I hooked up a projector
to the VGA connector. I also had Powerpoint open as I was going to project a
Powerpoint presentation. This is on a Dell laptop.

This is my first attempt to make some use of this forum. With respect to
desktop icons, I have only read posts concernig the size of the icon being a
problem. I was very surprised nobody mentioned a problem similar to mt own,
which is that when I personalize an icon (By right-clicking over it and then
click "properties" and then "change icon" and then select from dozens of
choices.) What happens is that over time, a number of these personalized
icons "morph" into a generic-looking icon that is very plain, has no color
(well, it's white.) I don't know if perhaps I have some kind of virus- well,
basically, I don't have a clue whats going on or what the remedy is.
