I just uploaded Windows 10 and now every time I am working with my touchpad there is some type of frustrating issue! Sometimes the font sizes change for no reason - on the web or in a document. The cursor jumps strange places for no reason, but usually when I am touching both the main pad and the lower left pad. I often have trouble cutting and pasting, etc. I'm working on a writing project and don't have time for this. Need help! Thanks!
