Thanks for replying,

yes, Form.Dataenvironment.

My form is just a simple data entry screen with simple code in the command buttons.

Top = go top
prev = skip -1
next = skip +1
Bottom = go bottom
Add = append blank
edit = I just enable the text box
Save = =tableupdate(.t.)
Revert = =tablerevert(.t.
Exit = thisform.release

the table buffers are all set to 5

all the control source of text boxes are in one table and still if I run the form and press exit the table disappears.
