In your observer swarm, check where you have the button click sent.  IN
many swarm apps, it is a Grid2d object that receives the message you
indicated in the observer.  The Grid2d only knows where the agents are
if the agents have a command in them that puts them in the grid.  In
heatbugs, it is in the step method, and each bug first puts a nil where
it is, then looks for a new spot, and when it finds one, it tells the
grid something like (I recall) [world putObject: self AtX: x Y: y]. 
When the Grid2d receies the right click at that (x,y), it will check to
see if an agent has registered itself there, and give you the probe,
just as it would for the old agents.
