anything more to install a new language?

<br />I downloaded the pgadmin3.mo file<br />I created a directory named de_DE within i18n<br />I copied the
pgadmin3.mointo that directory<br /><br />no, within File / options / general / user_language I can select de_DE
(Deutsch)<br /><br />but after closing the dialog it falls back to Default ... or whatever else was selected before.<br
/><br/>When I change to ca_ES (Catalá), all works fine (besides my spanish), and also Suome can be used....<br /><br
/>Whatam I missing? <br /><br />best wishes<br /><br />Harald<br /><br />-- <br />GHUM Harald Massa<br />persuadere et
