>After adding a large number (c. 2000) of labels to a container on a form using addobject() (this being to prepare a scattergram/map), closing the form is very slow, up to 8 seconds, depending on the number of labels added. Is this Fox cleaning up memory? And might there be a way to speed it up! Thanks.

Denis,
Natural result with too many objects.
Consider other means :
-Using nonobject elements like line, box.
-A graph interface
-A grid
