Adding foreign keys

The add constraint foreign key dialog does not appear
to be working correctly.   It doesn't offer any column
choices in the 'referencing' drop down box in the
columns tab.  I have a table selected that has the
primary key column I am trying to reference.  I have
tried this on multiple tables, both when creating a
new table and then also when creating a new key on an
existing table.  I have had to add the foreign key
just using an SQL statement - which works fine.

Also, if I want to create a foreign key that
references the primary key in the same table
('child_of' type columns), I am not able to do a self
reference to the table untill after it has been fully
created.  I was sure if this was a bug or simply
hadn't been implemented yet.  I seem to recall it
working in previous versions of PgAdmin, but I could
be mistaken and I don't have them around to test.

Here is my configuration
PgAdminIII 1.2.0(Nov 29, 2004)
PostgreSQL 8.0rc1(installed using pginstaller)
Windows XP Service Pack 2
