SHP2PGSQL-GUI plugin not visible in 1.16

Hi,

I have this code in my plugins.ini file

; POSTGIS SHP2PGSQL-GUI (Windows):
;
Title=PostGIS SHP2PGSQL-GUI Console
Command="$$PGBINDIR\postgisgui\shp2pgsql-gui.exe" --host "$$HOSTNAME"
--port $$PORT --username "$$USERNAME" -d "$$DATABASE"
Description=Open a PostGIS ESRI Shapefile loader console to the current
database.
KeyFile=$$PGBINDIR\postgisgui\shp2pgsql-gui.exe
Platform=windows
ServerType=postgresql
Database=Yes
SetPassword=Yes

but the plugin doesn't appear in the list of plugins in pgAdmin (v 1.16).

I can copy the PSQL plugin text (below) and get 2 copies of that plugin
visible and running, with

Title=PSQL Console
Command="$$PGBINDIR\psql.exe" --host "$$HOSTNAME" --port $$PORT --username
"$$USERNAME" "$$DATABASE"
Description=Open a PSQL console to the current database.
KeyFile=$$PGBINDIR\psql.exe
Platform=windows
ServerType=postgresql
Database=Yes
SetPassword=Yes

Any ideas?

Thanks
Dan
