Hi van...you might try the bit of via code that I found...it seems to wrk ok for me
Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
On Error GoTo ExitSub
Application.EnableEvents = False
If Target.Value = "" Then
Dim response As VbMsgBoxResult
response = MsgBox("Are you sure you want to delete/remove this cell?", vbYesNo + vbExclamation, "Warning")
If response = vbNo Then
Application.Undo
End If
End If
ExitSub:
Application.EnableEvents = True
End Sub
hope this helps
