Hi, 
 I am also facing a problem with DbVis.
 (well i know this is not the forum for it..but if anyone can help out :) )
 I have loaded the driver org.postgresql.Driver in it..
 but it fails to connect..(i am giving the proper user/passwd)
 does not give any errors...just stays as it is.
 has anyone experienced like this before?
 thanks for any help
