Hi John,
Local apps only works on 9.04 or later.
Here's my lts.conf
[Default]
LDM_DIRECTX = True
XRANDR_DISABLE = True
X_RAMPERC = 80
X_MODE_0 = 1280x1024
LOCAL_APPS = True
LOCAL_APPS_MENU = True
LOCAL_APPS_MENU_ITEMS = firefox
SEARCH_DOMAIN = 192.168.0.1 || Change this for your own network
DNS_SERVER = 92.168.0.1 || Change this for your own network
RCFILE_01 = /etc/init.d/chmod-resolv.sh
