Question #404001 on Sikuli changed:
https://answers.launchpad.net/sikuli/+question/404001

Description changed to:
usage is correct - problem fixed with 1.1.1 nightly 2016-11-29
-----------------------------------------------------------------

I don't understand, why this code hangs up (I use latest 1.1.1 nightly
version).

def myhandler(event):
    print "Seen"
    event.stopObserver()

img = "a.png"
reg = Region(417,895,209,185)

reg.onAppear(img, myhandler)
reg.observeInBackground(1)
reg.stopObserver()


# img is on the screen, so myhandler should immediately run and print "Seen". But I see the following:

--------------------------
Exception in thread "Thread-11" Traceback (most recent call last):
