WindowsForms C# non firing click event [closed]

Question

I am creating my own button element. When the button is clicked, it works correctly. But if you press the button quickly, then some of the clicks are ignored. In the button class, which is inherited from the Control class, in the OnMouseDown method, I added information to the console about the button being pressed. I also added information about the button click in the click handling method in the main form class, which, of course, is inherited from the Form class. The method itself was automatically created from the constructor.

Why is part of the clicks in the main class ignored?

It may be that the double-click event is being fired instead of two clicks.

You could try handling the DoubleClick event as well and check if it is fired.
