[Pharo-users] PBE.image

I run Pharo on Linux and tried to start Pharo with the PBE.image, that is offered as an add on to the Pharo by example book. I copied PBE.image and PBE.change to Pharo-1.2.1-OneClick.app/Contents/Resources/ (where pharo.image and pharo.change reside as well) and changed the last line in pharo.sh from "$ROOT/Contents/Resources/pharo.image" to "$ROOT/Contents/Resources/PBE.image" When I start the shell-script nothing happens. What is wrong with my experiment. With pharo.image pharo starts properly. I tried to change the setting in pharo.ini from pharo.image to PBE.image as well. No success! What is wrong? Regards B Blochl
