I am running autocad lt 2007 on my pc and laptop. On my pc I can zoom in and out with my wheel just fine. I use a logitech trackman wheel. On my laptop on the otherhand I can't zoom in and out with the wheel, it only scrolls. I can't for the life of me figure out what the heck is wrong. I've tried every setting on the mouse options in the control panel and still it won't zoom! Can someone please help.
