I appreciate the help. It appears to have solved the problem. Again, knock on wood, but it's looking good. ^
It's also good to know that the difficulty is not with Windows 8, as I had assumed.
UPDATE: SPOKE TOO SOON. This next a.m. the font size again changed, on its own, despite disabling the touchpad and slowing down the mouse. I am thinking that I probably got what I paid for on this laptop, and I am still happy with the purchase and can live with the difficulties, which I am now guessing might be undiagnosable and unsolvable. Anyhow, for the purposes of this thread, at least I have discovered that it is not a Windows 8 problem.
Well I can't think what else it could be, doubtful it would be a key combination and it sounds very frustrating for you. I once lost hours of work when I managed to hit my touchpad twice by accident and that managed to shut down the programme I was working on without saving anything. I was on a train and the movement of the train had jolted my hand onto the pad, the resultant closure caused me to say "Fudge" rather loudly. After figuring out it was that that had caused it, I disabled it and then when back home I found a piece of plastic which I cut to the same size and put that over the top of it, just in case.
