How is it "failing" -- it works for me -- when I click on the rectangles, I
get a mesage on the console saying which one got clicked. What does it do
for you?
I just tested it with wxPython 2.9.4, on a Mac.
Maybe an issue with 3.0?

this search is ugly -- but if you added aname attributre, you could just do:
print obj.name, "hit!"
