List View or Table View refreshes when adding records
When you commit a new record to a sorted found set displayed in List View or Table View, the record moves to its proper location in the sort order. Therefore, the new record may move elsewhere in the list or table and might not appear in the current window. To have FileMaker Pro display a confirmation dialog box before each record is committed, thereby preventing an accidental commit operation, see Setting the automatic record-saving option for a layout.
Note  To keep new or changed records in the same position in the sort order, see Options for sorting records.
