Mouse not registering all clicks

I am performing CPS Test on a website and it is not registering all clicks. What could be the possible reason.

Do you have any other OS (like Windows) where all clicks are being registered? It would help to understand if the issue only occurs on Zorin OS. Some other info that could be helpful:

  • Is it connected via Bluetooth or a 2.4GHz dongle?
  • Or is it connected via cable? Directly into your computer or via a hub?

If it's an USB mouse wire or wireless you may want to try different ports as their are a couple of different USB nowadays.

Have you looked at Settings>Mouse and Touchpad?
There is the ability to "Test your Settings" button located at the at the top of that screen.
You can also make adjustments and test them there.

I tried that too—switching USB ports actually helped in my case. I also used an online click tester to test if the mouse was responding properly after switching.
