I just downloaded 9.0 onto my laptop and desktop Windows XP machines. .Nether one could run the stack builder. Windows would fault any time I tried to run it. I tried inputing the proxy server but that did not help. This was at work where there is a proxy server. I tried this at homw wiith the laptop but got the same error: Could not open the specified URL. ray -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
