I just discovered, that the attribute "@shared 1" (used for [hit.window] or [jit.pwindow] objects) doesn’t work (yet?) with 64bit Max on OSX. Did you have any idea how to workaround this issue?
I need to add to my project simple "preview" based on [jit.pwindow] object inside the main window of the project and a separate [jit.window] object for fullscreen on secondary monitor. Simple… in theory ;-)
