If the game mode is set to game only and "Set Show Mouse Cursor" is set to true some click events appear to get dropped
Expected: The Print string that says "Click" would fire everytime the left mouse button was pressed
Result: The print string that says "Click" does not fire all of the time once the game mode has been set to game only and the mouse cursor is set to show up
