problem connection to postgres 7.3

Hi,

I've just installed Postgres 7.3. I'm trying to connect to it using pgAdmin
1.4.12 (tried 1.4.1 too). I get the following error :

An error has occured in pgAdmin:frmConnect.cmdConnect_Click :

Number: -2147417848
Description: Erreur Automation

Do someone know something about that ?

Thanks

Didrik
