About a week or two ago my PC mouse/cursor became supersensitive. It started highlighting huge swaths of text at the slightest move, and did all sorts of unwanted and unexpected reformatting at the lightest click.
I hate this. What gives? Did I flick a switch somewhere that I can unflick now? I want it to behave the way it used to. Any ideas?
NOTE: I did some computer housecleaning around the time of the change. I ran a tune-up program that was intended to find and correct errors in my files, registry, etc. Could this have triggered the change?
Thanks all, in advance.
