Network manager doesn't autoconnect to wireless networks in stable?

[chombee <chombee@lavabit.com>]

Hi,

I've noticed that in Debian 5 network manager doesn't automatically 
reconnect to wireless networks that it has connected to before, e.g. 
after logging in, you have to use the mouse to tell the applet which 
wireless network to connect to. I've been googling and looking through 
the man files but I can't seem to find out why the behaviour is disabled 
or how to re-enable it. Is there a way to enable network manager's usual 
automatic reconnecting behaviour in Debian 5?

Thanks
