hello,
i give 0.43 an other try. it look like being seriously broken with GOP.
by example, i try opening my lighting patch : http://www.chnry.net/ch/?092-Lighting-for-Pure-Data-lightboard&lang=en
then opening "memoire_lumiere" subpatch : all GOP are not visible and i've got error in pd log. then, closing everything give lot's of errors : error: .x857a0a8: no such object and i have to quit pd.
