hi everyone, 

I am new to Sikuli and am walking through the tutorials. I ran up a problem with one tutorial (http://sikuli.org/docx/tutorials/sliders/sliders.html). It's the one about sliders. If I use the code below I get the message of the summary.
t = find("Alertvolume-1.png").right().find("3.png")

The images mentioned are visible on screen. Futher I get the errors below.
