My middle mouse button does not allow me to rotate the part. Does anybody know the fix for this? I am currently running SE -v20 on windows xp sp 2. Both have all the latest updates.
Usually, you have to uninstall the MS Intellimouse drivers and go back to the generic mouse driver.
I also had another brand of mouse that worked great until I installed their software drivers to get full functionality of the multi-button mouse, only to loose what functionality I prefer.
I have also seen where the middle mouse button gets mapped to a different function. If your mouse settings, make sure middle mouse button = middle mouse button.
