i think it's rather due to the version of PDP, this works fine with PDP 0.12.2.
ooops, sorry, it was me, i have a patched PDP so that's why it works here.
i've uploaded a new archive where i basically removed the pdp_xcanvas object for now.
so please, download again : http://ydegoyon.free.fr/pidip-0.12.10.tar.gz
