[SOLVED] Problem reloading pages when editing values

I have installed gallery2 on my windows-apache system and its all very nice and working fine from the local computer (using 127.0.0.1). But when im browsing the site externally i have this very annoying issue:
When logging in to my galler2 site I enter username/pass and then the page tries to reload but fails. If i go back to main.php and hit reload the page loads and im logged in. And whenever i try to edit anything, like adding descriptions to pics and albums, i get an error when the browser reloads the page. Errors like "cannot display the webpage". If i go back to main.php and reload its ok again.

Can you guys help out or point me in the right direction? I sure would be apreciate it!

My specs:
Gallery version: 2.3.1
PHP version: 5.2.14
Webserver: Apache 2.2
Database: MySql 5.1.50
Activated toolkits: NetPbm, Gd, ImageMagick
Operating system: Windows Vista Home Premium 32bit
Browser: any
