Thanks for replying, and sorry if I made a mistake its my first time to use this site.

The form that I have is just a simple data entry screen werein I have the basic command buttons, top, prev, next, buttom, add, edit, save, revert, and exit, all the commands are simple like go top, go bottom, skip -1, skip +1, append blank, =tableupdate(.t.), =tablerevert(.t.) and thisform.release. In the database environment I set the table bufferings to 5 and still the tables and views keeps on disappearing.
