do you have any other libs loaded besides Gem? i'd like to know, which.
i had a handfull of problems with gem before and it turned out that
these problems were conflicts between gem and other libs (pidip,
gridflow, 3dp and maybe some others). when testing gem, try first to
load it alone, with no other libs loaded. it also seemed to me, that the
order of how the libs are loaded has some effect, whether gem works
correctly or not.

this might be not a problem of [pix_film] or [pix_image], but of
[pix_texture]. send a message [mode 0( to it, then the texture should be
applied as expected.
