i use wmii-3.5.1 in Arch Linux. some times while wmii is running, it stops takiing any actions from keyboard, i mean, it does not take any action no matter what keys i press but in the end i can use "C-M-backspace" to kill X and start again, eveni can do "C-M-F2" to go to another virtual terminal but wmii itself does behaves as if keyboard is not present, though i can move the mouse without any problem.
