Ok, I downloaded blender and it runs fine, and I was following the snowman tutorial at the blender website, and I get to the part where it tells you to press number 3 on the numpad or number bar to switch to side view to get a better perspective on a cone for the snowmans nose, but when I press 3 it makes everything dissapear!!! even when I look around the grid nothing shows up, and I cant select anything either! But when I press 1 on the numpad/bar it brings everything back just the way it was.
Also, the tutorial says that pressing F9 should bring a drop down menu, but all it does is minimize the Blender program.
I’d like to note that I am using a Macintosh PowerPC G4 with a wireless 3-button mouse attached, if that makes a difference.
