Window is resizable
Make the dialog window resizable. Enabling this option allows the user to resize the dialog window either by dragging the title bar, or by pressing the maximize/restore button. This option only applies to dialogs using the Standard and Bordered window styles.
Tip: To manipulate the size, position, visibility, etc. of objects when the dialog is resized, use the On Size event of the dialog's Script tab.
