Problem with tables that have more than 1 field a pkey

Hi!

I have the following problem with pgAdmin, if a table has a primary key
comprised of more than 1 field, pgAdmin cannot identify specific rows. So
when I try to do an update or delete a row, pgAdmin updates or deletes ALL
of the rows in the table. If the table has no primary key or a key with 1
field, it works OK. I'm using pgAdmin 1.4.12, and postgresql 7.2.2.

Thanks in advance for any help,

Andres
