After installation, I had no problems using wireless. Next, I added a new user (with administrative access). Now, when I log in as the new user, nm-applet doesn't appear in the panel and there is no wireless access.

I've tried adding the Notification Area (nothing appears), making sure that the new user can connect to networks, etc with no success. System Monitor shows that nm-applet is sleeping. When I restart and login as myself, everything is still working fine.

Computer: Dell Latitude D600
- Ram: 1 GB
- HD: Hitachi ATA HTS541680J9AT00
- OS: Win XP Pro & Ubuntu 10.04
- OS: win XP pro 32 & Ubuntu 10.04
- Network Controller: Broadcom BCM 4306

What additional info should I provide to assist diagnosis?
