gpe-taskmanager - lists windows and kills errant programs
gpe-taskmanager
gpe-taskmanager is part of the GPE Palmtop Environment. It displays a
list of windows on the current display, and allows the user to kill the
task which owns a particular window. This can be helpful if a program
has hung and is no longer responding to direct user actions.
