So I just got this new Lenovo Flex3 computer, and it's totally awesome. But a huge problem that I can't figure out how to fix, and I know it's not actually how to fix, but I don't like it, I can't move the mouse using the trackpad while pressing keys on the keyboard. So like when I am typing a report, can't move the mouse. When I'm playing a game, I can't move using WASD and look around at the same time.

My laptop is Windows 10. Anyone know how to solve my problem? Thanks :)
