For quite a while I have been using a Microsoft Wheel Mouse on my iMac. In order to do this, a driver must be loaded, and applet then shows up for the Microsoft Mouse in System Preferences. As I said, this mouse has been working perfectly for perhaps a couple of years now.
Recently the mouse has become flaky when I press down on the scroll wheel. I have the wheel button set to bring up the Dashboard. From the beginning, a single press on the wheel would bring up the Dashboard. However, recently pressing on the button is erratic, perhaps taking 10 presses to bring up the Dashboard.
My question: is the mouse simply going bad? Alternatively, is there a way to "clean" the button mechanism to restore operation?
