You started to create a selection set of objects using a window or crossing selection, and then you panned or zoomed to select more objects. Objects that were no longer displayed on the screen were dropped from the selection set.
To prevent objects from disappearing from the selection set, you should complete your selection of objects in view before you pan or zoom to a different part of the drawing.
