RMB + Direction – Look Direction not working for me

I have tried numerous times and can’t figure out why when I hold down the right mouse button and move the mouse it doesn’t work. It immediately zooms off into the sky and I can’t get it back. Can someone tell me if I have a setting messed up. I can’t even move around the viewport in perspective mode. MMB + Direction –
Pan Direction also doesn’t work. The only one that works is LMB. I am using version 1.8.
