I can confirm that fbclient.dll looks for firebird.conf at one folder above. I don't know why it takes too long but this is something OS (or your environment) specific. To avoid it i would try to set FIREBIRD environment variable to the fbclient folder. It should be done before fbclient is loaded by application. Hope it helps, Vlad
