Three Button Mouse Problems

I am an intermediate level user of Sketch Up, and for some reason when I opened my model today the rotate command was not working when I depressed the scroll wheel on my mouse. I have a new cordless Logitech mouse, and instead of rotating when I depress the scroll wheel, it tries to zoom in. Does anyone know how to fix this problem?

Yeah, although what you're trying to do is not rotating, it's orbiting. Rotating is when you spin an object around; orbiting is when

you move the camera (your point of view) around a stionary object.

Go to your mouse driver application and change the function of your scroll wheel button to "middle button." You may have to look for that function on a list of "Other Functions."
