Action Hotspot Issue

I am still learning programming in Notes and I have a basic question.

Why does an Action Hotspot process when you right click on it but an Action Button doesn’t?

On a Action Hotspot if you left click and hold and then decide not to select and pull away the action still goes. On a button this doesn’t happen.

Just wondering if there is a way to stop these two things from happening on a Action Hotspot.

I am just using Formula Language on the Hotspot no scripting. Nothing crucial just wondering?
