Probable bug in ver. 0.1.9.9 if someone else can test and reproduce also.
QBW widget won't monitor DBUS if @Sight is checked.
IMO @Sight should only disable updating during locked or offscreen but still keep the widget ready to intercept any dbus commands that are matched by pattern.Having the dbus monitoring off as well is equivalent to having the widget "disabled".
Correct me if I am wrong.
