Actually, I realize that the dialog underneath the warning dialog (entitled "Wii-Fi Network Authentication Required") is still active;
I can check the "Show password" box, click on "Connect" again (no effect) or on "Cancel", which closes both dialogs alltogether.
(I attach a screenshot to make things clearer)
So this seem to ne not so much a freeze than a focus problem ?
I tried to change the window-manager (metacity instead of gnome-shell),
but the problem was still there.
