Back button and Task View on mouse

[dr.tro...@gmail.com]

Hello Everyone, on chrome or any program I am using, if I hit the back button (on my mouse) it opens task view and also goes 'back' on the page I was on. This is extremely annoying and it started doing it a couple weeks ago. I've had no luck looking for answers on Google. Can anyone help me? The mouse i'm using is a Logitech MX Master mouse, and I running Windows 10.

Thanks,

Dr. T
