I know, it's probably only me again. Anhow, maybe someone can recreate this behaviour.
Take this CAPX and run it - is should work just fine...
Than, edit the code: Select the object called "outletBorder" and add the physics behaviour to that object. Now run the Capx again....
Here, it crashes (greey screen with a black line) on CHROME and FIREFOX...
Is it just me?
