2D pose estimate button problem

edit

I'm trying to do the autonomous navigation tutorial I am having problem on "2D Pose Estimate" button in rviz when i click on it and drag an arrow to set the initial location for turtlebot, the red particles dosen't appears and also location of robot dosen't changes.

fixed frame is set to /map Target frame is fixed frame

Rviz output:

[ INFO] [1343324167.032855241]: Setting pose: -0.286 -0.421 -2.323 [frame=/map]
