I use a 3Dconnexion SpaceExplorer mouse and am having a problem with it. It's been great for a few years but now, even with my hand off the control, my parts and assemblies won't stop rotating. The speed of rotation increases as I increase the sensitivity of the mouse from the control panel. I've installed the latest driver and that made no difference. Ditto for re-booting. No response so far from tech support at 3Dconnexions. Other than a two-pound ball pein hammer, does anyone have any suggestions on what I should try next?
