Is there a way to control at which position the main Pd window appears on the screen on startup? For an individual patch, I can write desired values into the canvas definition line "#N canvas X Y ..." in the patch's pd file - but what about the main window/console?

I suspect this may be possible by hacking pd.tk, but as I'm unfamiliar with Tcl/Tk I don't quite know where to look. I'm running Pd version 0.39.2-extended-rc3 on Win XP (gave up on Vista for now).
