Thanks for the reply. Yes, at the moment, I'm using 0.42.5 Lucid 64bits. I just tried to install the 0.43.5 Lucid 64 DEB with no luck. I think I should compile... The only soft I compile in my life is Blender from SVN. I don't think compiling PD would be difficult... but I don't find a step-by-step tutorial to do it. Do you know any?
