In the past I’ve had great experience with Logitech. I Don’t know why I’m complaining now. This has been happening as long as I’ve had my current mouse. In other words…years. The mouse constantly thinks a click is a double click! If you want something that really can aggravate you then this is it. It’s is a productivity killer! I curse it, I slam it down and/or very rapidly repeatedly click the mouse buttons until it behaves…for a while!
