Usually, users can drag their window by clicking on the window title then dragging the window to its new the selected area. But sometimes, you may not have a window title or the window title is not visible.
The use of the DRAG WINDOW command might just be the solution. You jus need to create an invisible button in the background of your form and place in its script a call to DRAG WINDOW that executes for the On clicked event. This command does not requires any parameters and will allow the user to move the window by clicking in it and dragging it.
