I installed klik 3 or 4 times and it would not work, but then after I rebooted it worked fine.

Now I have to check fstab for extra entries, but klik does NOT work no matter how many times you reinstall and restart Firefox (until a full reboot).

Also, what the heck is this mysterious ALT-F2? Is that a Firefox command? Which window should have focus because ALT-F2 does nothing I can see. Of course I'm running Fluxbox and sometimes Rox under Vector 5.1 standard........ So maybe it's a KDE command. I dunno.
