Yesterday it was going to upper right corner, today upper left. It is a blinking white spot about the size of *. I have 2 or 3 windows open and it will randomly return to the window in the upper left corner. It would be hard to do a screenshot or video since it isn't obvious what is happening. Plugged in with wireless mouse it now goes to upper right. As a touch screen, it seem to work ok, but I need touchpad and wireless mouse to work. Oops, now, even with touchscreen, it goes to upper right. I've had it for 3 or 4 years, maybe it's lifespan is up, but it was a lot of money and I hate to give up on it.
