Hi all,

Installed mongrel after I finished my application so I could run it as a  
windows service… Installed fine and when I pointed at  
[http://localhost:3000/system](http://localhost:3000/system) the homepage came up fine. But when I  
clicked the links the port number(3000) disappears, for example  
([http://localhost/lab/system/show/2](http://localhost/lab/system/show/2)) and i get a 404 not found error.  
Any idea whats up? My Application works fine when I run it with  
script/server.

Thanks
