Look at pdtk_canvas.tcl, that's where this is happening.  The difference
is that with a new file, Pd is generating the x,y coords to place the
window, and with open file, its reading them from the first line of the
patch.

I use GNOME, so I am not well versed in all these issues.  But I'm happy
to help you figure this out so that we can easily support all the
various WMs that people want to use.
