Seems to be a hardware problem: "In the Logitech support forum, a Logitech support staff posted a solution that worked for me. You have to remove the battery and press the buttons for 30 seconds to remove static electricity: http://forums.logitech.com/t5/Mice-and-Pointing-Devices/Performance-MX-mouse-double-clicking/m-p/709722/highlight/true#M36353
Takes 1 minute, give it a try :)" - seems to work for me.
