hi again
I have not created any thread and I am using the default string.
maybe i resuse queries .but But first I close and clear them.
Also, keep in mind that this structure was already working correctly with ADO,
I changed the ADO Components to FD just to get a better and faster build.
alse my quries rows has read and edit.
Thank you for your time to solve this problem
