If a window is off-screen when in 4D's Design environment, bringing that window onscreen can be somewhat difficult. This can happen due to a screen resolution change or the 4D application window being resized (Windows OS only). That is no longer a problem in 4D v11 SQL.
The 4D Pop Windows component offers an option called Recover, that brings off-screen windows onscreen. This component also includes this Recover functionality in some of its other features. The Recover functionality brings the current window onscreen and positions it in the top left corner of the 4D Window.
