I'm running kmyfirewall under KDE3.1.1a. When it
starts, the initial setup stage seems to work, but then
it brings up a "main menu" (with stuff like "start
wizard") and a main window.
The main menu is completely unresponsive. Nothing
works, not even the close button. At this point, I
stopped trying anything else.
(I also noticed that the statusbar on the main window
said "firewall not installed". This is not true, I have
some iptables rules already set.)
