When a RentMaster window is closed, it automatically stores the location of the window so that when it is opened again it will be opened in the same location and same size as when it was last used.
The problem that can have is when someone makes the main window smaller, the location of the window may now be outside the boundaries of the main window. This results in a number of people thinking the software is not working because they click a button expecting a window to open, which it has, but they can't see it. They can find the window again by clicking and dragging the scroll bars inside the main window, but people often overlook these scroll bars.
So now when a window it opened, if RentMaster determines the window cannot be easily seen inside the main window without scrolling, it will automatically be moved back to the top left coordinate of the main window. From there it can be manually repositioned somewhere else again if required.
