i start pekwm with startx , in my .xinitrc file i have exec pulseaudio -D & conky -q -d -x 1576 -y 0 -c ~/.conky/conkyrc & exec pekwm
without moving the mouse or focus anything i press the cmddialog and run pidgin is fine by now then i with the mouse and without focus anything i change with the wheel the workspace and try run cmddialog the the key combination again , and don´t work i need get something focus first like root menu , etc, i think this behavior is not ok/normal.
