Randomly, when typing on keyboard, my font size changes to very large, then small and sometimes just back and forth in size.  What causes this and how can I stop it?

Could be a stuck Ctrl key on the keyboard, then when you touch the mouse pad or scroll it zooms in and out. Try tapping on the control keys, there may be 2 of them. Tap them a few times and see if it stops. You can run your fingers over all of the keys a few times, it may unstick a stuck key.

If I am helping you with a problem and I have not responded within 48 hours please send me a PM.
