Using 'screen' successfully

[Troy Chinnery]

I am having the same problem as this guy: 
http://bf1942.lightcubed.com/forum/viewtopic.php?t=1935

When I start the server without a screen I can use 'admin.runNextLevel' and 
the server will restart itself with the next map, however inside the screen, 
when the server quits (to restart), screen thinks it has died and so 
'terminates' itself.

How can I make screen wait for it to restart? Is there a better way?

Thanks in advance,
Troy
