Thank´s Fred

The problem is, if i open the project, allready with the database opened and go to the command window and type

use mytable && table is not marked beloging to the database

but if i do this

close all
open mydbc shared
use mytable && no problema


I already validate the database, recreate the database, rebuilt the project, delete the foxuser.*, work in a diferent machine.

What´s happening here.
