I wanted to make it a subclass of SystemWindow (I'd actually prefer StandardWindow in Pharo but there doesn't appear to be an equivalent in Squeak). But when I do, the step method doesn't get called. (Nor does stepAt:) (And StandardWindow behaves the same.).
To get your SystemWindow subclass to step, send #startStepping. I don't know if it's any better, but when I create my own morph-in-a-window, I usually don't subclass SystemWindow, but add my morph to a window using openInWindowLabelled: or addMorph:fullFrame:. I feel like I have a little more flexibility if I later want to use it not-in-a-window.
