Server not visible in client

I'm trying to add a server in pgAdmin 3 to get开发者_开发技巧 started, but somehow server is not added. I fill all the fields as described here but after OK button is pressed client writes in the bottom left corner "Connecting to database.... Done." and that's it. I presume it's quite trivial, but can't figure out what's wrong. Please, help.

NOTE: Using win xp.

Your sure after you see the done text there is no server group name in the Object Browser?

Normally after you see the done message click on the server name in the object browser. You named this when you created your connection. Once you click it, it will open up a tree view of objects for you to explore.
