Technically at this time, no.

But in theory, this database could be accessed by multiple systems
at the same time...  And thus it is safer to refresh the entire table
then it is to reread just a single row.

Reading the table from the database is very fast...  The majority of the
time involved in the gather_data routine is the Dialog window redrawing
the
data....

	Quite possible.  I just did a simple check to see how it woruld
work.

	Yes...  It could...  But even if the data is indifferent
position,
I don't mind the cursor being where it was previously. =20

	These are software titles, etc...  (It's a auditing system...)

	So if your editting "Norton Utilities v2.0", probably you'll
want to edit something nearby...

> while loading the table from the DB :

	It is possible.  For some reason (I forget), I did not want to
do that......  I'll make a quick model...

	Possibly lost in the email was a small issue...

1) SetSelected does not reposition the list to be in the visible area.
Is there some other way to force the selectedvalue to be in the visible
area of the dialog?
