Hello Dennis,

I have searched for Border_Dialog at help, there is 9 results, one of them is ModalPanel:

There are no new properties in this class. The following properties are set to give an object the proper modal appearance and behavior: Caption_bar is true, Border_Style is set to Border_Dialog, Minimize_Icon is false, Maximize_Icon is false, SysMenu_Icon is true, and Modal_State is true.
Not sure if in the other classes is fine or not.
