pgAdmin bug? creating functions

I am having problems creating functions with PgAdmin. I have searched the 
lists at archives.postgresql.org/pgadmin-support, but didn't find anything 
about it.

The basic problem appears to be that PgAdmin may not be setting the 
search_path properly when it issues its updates. The scenario is this:

I am working in a schema which is neither the public schema nor the name of 
the current user. When I try create functions that take arguments that are 
table names, postgres says it can't find the table. For example, if the 
user is xxx and the schema is sss, the following should work
        create or replace function sss.doit(sss.mytable)               ...

If I create this function using psql, it works just fine. However, when I 
look at the function in PgAdmin, I see this
        create or replace function sss.doit(mytable)

(mytable has lost its schema prefix). Mods to the doit function using PgAdmin
result in the following error:
        ERROR: Type "packet_tbl" does not exist.

A similar problem occurs when creating triggers. If doit (above) were a 
trigger function (ie, returns trigger), PgAdmin lists it in the pulldown 
when creating the trigger, but when it tries to create the trigger, the 
following error occurs:
        ERROR: CreateTrigger: function doit() does not exist.

I think it might be a search path issue that the GUI isn't handling properly.

Any help would be appreciated.
