Right mouse button only does not work in Minecraf?

It only works in Minecraft, it does not work in any other application. In Minecraft it is like that when I e.g. I don't want to shoot with a bow it breaks off all the time and starts again the same applies to potions and food placing blocks works with another mouse it doesn't work either

Then the option is probably set to the wrong or no key in the Minecraft settings. For this just in

Options -> Controls -> Use / Place and just click on Standard next to it.

If you have Minecraft in English: Options -> Controls -> Use Item / Place Block and to the right on "Reset"

Oh, I read the question wrong, sorry.

But then a question: does it really work otherwise if you hold the key? Because normally you don't keep the button pressed.

It is generally the case that when I hold down the right mouse button, he presses and releases it again

Of course that's stupid. Do you have a Logitech mouse? The problem seems to be known. (See link)

Apparently all that helps is to exchange the mouse, if you still have a guarantee on it.

But to test you can connect a different mouse if you still have one somewhere and test whether the problem still occurs. If not, it's up to the mouse.

No, I have a razer mouse
