Apple USB Mouse not working (right click) on MacBook Pro Retina Notebook
I have a USB Apple Mouse that worked on my MacBook Air where I could right click without having to click "CTRL" and then click. I have a new MacBook Pro 13-inch Retina Notebook and transferred the files and settings across on one user and if logged in as that it works, but I set up a new user and when log in on that my USB mouse will only right click effects if I do the "CTRL" and then click. I looked at mouse settings and can see no difference. It is driving me crazy. I have looked on here and googled but cannot out find a solution. I know the mouse can do it as can do it even not he same MacBook when logged in as another user... HELP!
MacBook Pro (Retina, 13-inch,Early 2015)
