First of all, all table are already set the buffer mode to 5.

I donno why if I code:

Select Master
append blank 
Thisform.Refresh

The FOrm will go to an OLD Record and try to overwrite the
old record.... the Recno is about Reccount-1 or Reccount-2 !!

WHile the Recno() for Blank record is '-1'!

Is it because there is a fix link on Order and Orderline??
but it work well when append blank in orderline.

Why Recno is changed when refresh after append blank in Order ??
