The mouse actually works properly - only - you have basically always the right middle finger on the right button lie, because he belongs there. But - at least I'm doing so - as an older person has to his fingers, not quite under control, so at the slightest movement with the re. Index finger on the left mouse button the re. Middle finger and reacts immediately with the right mouse button is touched only very marginally - and the context menu is displayed again, although it does not need. It's annoying because you then over and over again, it must first click away. And most then clicking the left button in the wrong place and you will open another menu which you indeed also did not want to open. It always comes back to delays in work progress.
