I have transformed my whole application to private data sessions
in the wish that every form were private, i.e. completely independent
from the others that used the same tables.

I have got frustrated once and again. The first, and tipical, was
to set up the environment for each form; I made the class and it
worked OK.

Secondly and most frustrating was that I could not open a table that
was already opened by the main program. I'll explain it further, as
I think is worth mention:

In the main program I open the 'setup' table, and it's intended to
remain opened for all the forms (all being written with 'public'
data sessions).
When I created private data sessions, I could not open 'setup'
again as VFP 3.0b told me it was already opened. I made:

select('setup')

and the answer was 0, so it was supposed not to be opened, but I
could not reopen it. Weird.
I had to redo a lot of routines as well as the main program, and I
finally got it to work but with a lot of work arounds.

As I see, the are not so private.

After some other problems, I got the following one: I included a table
in a form opened ReadOnly. The same table is in another form but is not
ReadOnly. Te result: no matter how private is the form, the tables
are opened the same that with USE...AGAIN, and if you open first the
ReadOnly form, the second is going to be ReadOnly too. Annoying.

I would like to hear from similar experiences and how you have
solved this annoyances.

Thanks,
Javier.
