I've read on other boards where other 2 in 1 type computers, with the touch screens, also have the same problem with erratic things like the cursor jumping around and where paragraphs are at times highlighted and then typed over without any notice at all. I believe, because of that, the problem resides within the Window's 10 OS rather than the individual computer. Just an opinion mind you. I do know I've lost many replies on this forum to the problem so quite possibly the problem has saved a lot of grief in addition to creating some (grief that is ... on my part).
