I just started with Blender and ran into a roadblock right on page one. The manual says you can scroll vertically while using the mouse wheel and press "shift": Does not work. Nothing happens. Horizontal scroll zooms the Apple screen. In short: except zooming in and out I can't do anything - none of the instructions work. I tried to reprogram the third button/mouse wheel but had to find out this is no longer possible in Snow Leopard. How can I get "changing the view" work in Blender?
