In my NEXT button:

IF NOT EOF('mytable')
SKIP IN mytable
ENDIF
IF EOF('mytable')
GOTO BOTTOM IN mytable
WAIT 'Currently Viewing Last Record' WINDOW NOWAIT
ENDIF
THISFORM.Refresh

I did have THISFORM.setbackcolor in front of the line THISFORM.Refresh, but that changed the background color of all textboxes to pale yellow whether they had values in them or not.
