how is the scroll wheel of the mouse supposed to control the view? I get a mix between zoom in/out and scroll up/down when I use the scroll wheel on my track ball. I am used from AutoCAD that I can use my scroll wheel to zoom in/out, with reference to my cursor location on the screen. is there something I miss as all I get is a mix between zoom in or out , but with the added feature of moving up or down.

I want it to zoom in or out only.

Thanks & Best Regards
