Zooming in and out on its own

[Nana2012]

My screen zooms in and out on its own. I want to keep it at 100 but anytime I touch the touchpad the screen starts zooming in and out. Any ideas on how to fix this?

Check with the computer manufacturer for a driver specific to your particular computer, its' keyboard and touchpad.
IF those are both updated then you may want to look closely at something call "gesture control" usually part of the driver for your specific touchpad and usually found in Control Panel
