I ordered a "second mouse" mouse. Since I often on different PC's build so that the required peripherals have been added. The mouse is quite small, but good buttons and wheel do what they should. Obviously, the mouse does but even more! When I had performed on a PC all settings (Windows 8.1) and wanted to test hibernation, this was not working. The known ways by software to break, brought nothing. Then I successively attracted all peripheral devices are - only after the mouse was removed, everything worked. With another mouse (Logitech optical mouse) also. What makes this mouse I have not figured out, but obviously there are disturbances / interruptions, do not let a PC come to "rest". Maybe even a defect !?
