[Cannot look left or right]

Thank you!!

 

[Cannot look left or right]

Nevermind .... after the first scenes in UNITY with the big wigs, look started working. Go figure.

[Cannot look left or right]

My apologies if this has been covered. All controls seem to work just fine except turning left or right. I'm unable to do this with the keyboard or the mouse. I can move left but it is a strafe, not a turn. I can look up and down with the mouse, but not left or right. 

Win10, 64 bit, most recent versions. 

Thoughts?

Thanks
