From our test2 bug scrub:
Nothing happens if you left click. Its not obvious you need to right click to
do anything. Left click should work.
What do you expect a single left click should do, launch gnome-power-prefs like
double left does?
No, it should launch the menu, like R click does.
Bugzilla'd upstream so all the developers can discuss.
fixed in 0.3.4-2
