[PD] trouble with pd-0.48-0 and multiple screens

Roman, for me it happens when i try to open (again) a pd-subpatch that i
previously placed on the second monitor (on the left of the main monitor) :
instead of appearing in its previous position, the window appears outside
the screen (on the right of the right screen), so you can't see it, drag it
Yes Nicolas, I experienced this with the "additional" monitor on the left,
so subpatches should probably have negative coordinates.

Hope this gives a clue to solve this, patching on two monitors is nice for
big patches...

all best
