Apogolies if re-asked, I have searched the mailing-list archive to no avail.

I am running a new ubuntu install on a netbook (Eeepc surf), with wired &
wireless networking available, both domestic manually-configured networks (no
dhcp).  I have added Manual profiles to both wired & wireless.  I cannot get
the default gateway (192.168.0.12) to configure, however.

I add two routes in the route config panel; one for 192.168.0.0/255.255.255.0
(no gateway), and one for 0.0.0.0/0.0.0.0 (gateway 192.168.0.12).  Having left
the edit dialogue, and applied, there is no difference to the routing table as
displayed with route -n.  If I re-enter the routes edit panel, I find that
it's collapsed the routes into one, being 192.168.0.0/255.255.255.0 (gateway
192.168.0.12); but there's no hint of the gateway in the route config.

Did you try adding the Default gateway to the Addresses section of the ipv4 settings tab instead of the routes section.
Also, If you have both wired and wireless interfaces active, I believe, it will always use the wired default route first if possible.
