When I try to zoom in & out of 1st to 3rd person with my mouse wheel, it doesn't work most of the time. I have the mouse option for "Mouse Wheel Zoom" checked on. The wheel works in every other way like when I'm scrolling through windows. How do I get it to work for zoom all of the time again?
Check your scroll " spacing " ... and try not to scroll in or out too fast. When I scroll out too quickly, this problem happens to me also. By spacing I mean when you scroll is it single/double/triple ( or more ) space ...
