Are Minimum/Maximum working?

[Kubrix]

    sbEnemySpawnInterval= new SpinButton
    {
      Nullable = false, Width = 100,
      Minimum = 3,Maximum = 20,
       Left = 10, Top = 100
    };

Cant change the value be mouse/keyboard

Looks like if you add your min or max value in when creating the SpinButton, it will allow you to change the values via the up and down arrows using the mouse.

sbEnemySpawnInterval= new SpinButton
    {
      Nullable = false, Width = 100,
      Minimum = 3,Maximum = 20,
       Left = 10, Top = 100,
       Value = 3
    };
