I hope this is a case of too much turkey over the holidays. I think i found a bug with Table Buffering. If i have a cursor with buffering set to 5(table) and change a value of an indexed field, then try to seek on the field i just changed, SEEK returns true (which it should not since the value no longer exists in the table) and the record pointer is left on the next record in the index order. I tested the following program in both VFP5.0a and VPF6.0 and got the same results. PLEASE somebody tell me i am crazy or i am doing something totally wrong.

Thanks

** SAMPLE CODE **
CLOSE DATA ALL

CLEAR
SET MULTILOCKS ON
SET SAFETY OFF

CREATE DATA IndexBug
CREATE TABLE Tbl1 ( field1 i )
INDEX ON field1 TAG field1

FOR x = 1 to 9
INSERT INTO Tbl1 VALUE(x)
NEXT x

CURSORSETPROP("Buffering", 5)

lRetVal = SEEK(7, "Tbl1", "Field1")
IF lRetVal THEN
? "Found 7 at recno ", RECNO()
ENDIF

? "Change value to 0..."
REPLACE Field1 WITH 0

lRetVal = SEEK(7, "Tbl1", "Field1")
IF lRetVal THEN
? "Found 7 again! at recno ", RECNO()
ELSE
?
? "It worked"
ENDIF
