Movin to amd64 debian testing, I am trying to runfrom X-system window manager a scientific application that requires (on 32 debian) libmotif3. Not present on deian 64 repositories. Is any equivalent. I am also trying to install window manager mwm. What about? I do not make use at 64bit of any desktop manager. twm is just too restrictive for my purpose. Thank you for answering. francesco pietra
