I have a Logitech MX Laser 1000 mouse, love the mouse. But the Middle scroll button does not pan when you hold down the wheel. And when you double click the wheel it no longer does a zoom extense. When you scroll the wheel it does zoom in and out. My mbuttonpan is set to 1. Any suggestions? Not sure if I toggled something on or off.
Install the Logitech Software.
Adjust the button settings on the mouse, set the mouse scroll button action too "middle button"
So far this has worked for the past 3 mouses I have used.
Did Shine's suggestion above work? I've seen too, at times, that the mouse software/drivers can be a problem. Leaving things up to Windows works better. It can vary from mouse to mouse.
If we attack this from the AutoCAD side of things, make sure you have the latest AutoCAD 2010 update. Here's the link:
It will tell you if you need the update or not when you run the installer.
Another test would be to try a new administrator user account on your system. That will let AutoCAD load with a clean initial setup. If the scroll wheel works in the new user account, then we can reset the program under your normal account. There's a couple folders and a registry key to delete.
Let us know!
