Sergio, sounds like your tables are being closed. Are you using private datasessions?

If not, check to see if the first form is closing tables when it closes

If so, and your second form is modal, check to see if it is defaulting to the first form's datasession. If so, the same problem with Form1 closing tables may be the culprit
