Have tried all of these solutions. The problem is that this appears to be some sort of "feature" that attempts to prevent mistouches. But it ends up in at least 50 problems a day. This happens when trying to move the mouse from one icon to another in the taskbar, or one tab to another in Chrome.
If move, wait a fraction of a second, release, okay it's no problem. But if make a short move and release, it immediatly jumps back. It's a huge pain. I've never seen anything like it. Hope to God they fix it or at least offer an option to turn the "feature" off. Seriously would not have bought this laptop if knew about this issue.
