I have a logitech K400+ wireless keyboard-trackpad. Sometimes, when I tap on it, it wroks properly, as if I had clicked on the left mouse button. Than sometimes tapping does nothing and I have to use a physical mouse button. I thought the problem was with the keyboard, but Logitech replaced it and I still have the same problem. It is intermittent. It worked fine for the last 3 days, now it has stopped again. Very annoying.
If I use any other wireless keyboard with a track pad, I don’t have this problem.
I tried replacing the driver. Windows says i have the latest driver.
Can you help?
