To display the Maximize and Minimize buttons on a form, you must set the form's BorderStyle property to Thin or Sizable and the ControlBox property to Yes. If you set the BorderStyle property to None or Dialog, or if you set the ControlBox property to No, the form won't have Maximize or Minimize buttons, regardless of the MinMaxButtons property setting.
Even when the MinMaxButtons property is set to None, a form always has Maximize and Minimize buttons in Design view.
Please don't bring any changes in the properties of the form. one thing you should have to do is> go to file> Option> current database> behind displays status bar is document windows option> please select overlapping window and then click ok.
