I just bought a new mouse and for some reason I can't drag the work around anymore.  I would usually hold down the scoll mouse button and I could drag around the drawing but now all it does is zoom.  I found I can hit alt to drag, but I really don't like this.  Is there a way to change it back to the way it was or change commands so the scroll mouse button drags the drawing around again.

I have had that problem before and changed the mouse settings to middle button.  It still will scroll but in cad it should pan. double clicking the wheel will zoom extends.

Yep, changing it to middle mouse button helped a lot more.  Thank you now I can pan in autocad once again.
