[SOLVED]When connected to Wifi - programs cant open display!

since today, whenever I am connected to WiFi (didn't try with ethernet), programs won't open any more, like this:

$ gedit
No protocol specified

(gedit:19767): Gtk-WARNING **: cannot open display: :0.0

or

$ firefox
No protocol specified
No protocol specified
Error: cannot open display: :0.0

for the connection I'm using testing/networkmanager 0.8.2-2, and I think it's becouse it's changing /etc/hosts when it's connecting, but it's changing it incorrect:
before its like in the "Begginers' guide":

127.0.0.1   localhost.localdomain   localhost laptop #hostname = laptop

after connecting:

92.168.0.48    laptop.WiFi    laptop    # Added by NetworkManager
127.0.0.1   localhost.localdomain   localhost laptop

after disconnecting:

127.0.0.1    laptop    localhost.localdomain    localhost
::1    laptop    localhost6.localdomain6    localhost6

BTW, when it's disconncted - everything works fine. if something is already open when I'm connecting - it's works fine.

thanks!
