3D view huge! I just started using this program yesterday. Was using 3D view fine, the entire image fit within the window and I could grab it and look at the different angles. Suddenly it enlarged to a gigantic proportion, such that it is useless. I have tried shrinking it back down using all of the available arrows, and the mouse. No luck. What mistake did I make to change the size, and how can I undue it? Thanks.
