Toolbars are quick and easy ways to perform a function of activate a form. In most cases you can have many different forms open at the same time and you can switch back and forth between them. However the nature of some forms are such that they must be completed and closed before you are allowed to perform any of task. These forms are referred to as ‘MODAL’. When a modal form is active, most options on the main menu will be disabled and any active toolbars will be temporarily disabled so that nothing new can be selected or activated until the current modal form is closed.
