Thanks for looking.

In QGIS I open up the Custom CRS definition dialog

Copy and paste a proj4 parameter line starting with +proj=  into the
Paremeters box

Copy and paste the Name into the name box.

Hit the little folder icon.

Nothing happens.  The number below the parameter line doesn't increment.

Hit OK and the custom CRS isn't added to the database.  Could my database
be unavailable somehow?

If I take a known, valid proj4 parameter line that QGIS has in it's
database, it it won't add it either (I miswrote this below)

I played around some more, and the test dialog WILL accept the custom
parameter lines, and does say they are valid, I just can't get my database
to recognize them.

I remember the database dialog box when I first installed QGIS, I think I
just took the defaults, in the DB manager it shows a SpatialLite entry,
but there's a flashing alert in the bottom of the window that says
"postgis No module named psycopg2"

If I highlight 'SpatialLite" and click the SQL window icon, I get an error
that says 'no database selected or you are not connected to it'.  I'm not
sure I have the necessary SQL programs installed.  in Synaptic I have some
sql packages, client libraries, shared libraries, python extensions.  Do I
need a specific core SQL package to get the database in QGIS to be
accessible?

In synaptic I tried to install python-psycopg2 and I got a warning that it
could not be authenticated and malicious control etc etc etc,  should I
install it anyway?

thanks,

Janet
