Ah ha, wait a second, my apologies, I completely misunderstood this response. Never mind - when I quit and restart Pd the behaviour is exactly the same on Mac and Linux, and I now understand that this is how it should be. Previously I was just closing the *patch* on Mac rather than quitting Pd entirely. On Linux of course closing the patch was closing Pd entirely no matter what.
