The problem here is that after you call Forward the database and the field use
the SAME string (at the same memory location), so when you change the field
string you are also changing the database string.
But before you call Forward, some of the field string and the database strings
are different string (=stored in different memory locations).
When you Load the database, you assign the same string of the database only at
these 2 fields:
> f1/text: db/1/1
> f2/text: db/1/2
When you click Forward, you assign the same string of the database at all the
fields.
I do not think that sharing strings between fields and database is a good
idea, but i can be wrong.
