title: Prevent Windows firing events during long touch of a button
body: <p>WinForms application.
  User touches a button (touchscreen) that causes authentication and the screen (A) is changed to another screen (B). If user continues to hold the finger on the screen (just for a second) the screen B has a button that overlaps with the button on screen (A) and the button on screen B inadvertently gets a touch and invokes an action that is not supposed to happen...</p>
  
  <p>How do I do to prevent this from happening?</p>
