Lately I've been messing about with drivers and things trying to do things I don't understand and have ended up with a few annoying issues. One is, I keep getting an up and down arrow on my taskbar and can't do anything at all with it. Can't right click, can't left click. I've gone into task manager and windows explorer and restarted it and it's fixed. Then the problem comes back a short while later. Anyone help? I have resolution and font size and appearance problems too but that's another story.
