Oh well, it > works now, that's all that matters. =) With shared memory enabled, tiles (for sake of discussion, 64 X 64 pixels of image data) are not transferred between Gimp and plug-in over a Unix pipe, but are written into/read out of a region of memory that is literally shared between the plug-in and the Gimp. This very much increases the rate of data transfer between Gimp and plug-in, A big advantage, but for reasons unknown, this mechanism is being corrupted on MacOS. The Unix pipe is working, however. You're probably happy it works at any rate of speed, so go have fun. But sometime or other, please visit http://www.xach.com/gimp/news/bugreport.html and fill out the form. Remind us that plug-ins aren't behaving well when shared memory is being used for tile transport on the MacOS platform. The problem may be that Gimp is making platform specific assumptions about shared memory. The problem may be that shared memory is not quite there yet under MacOS X Beta. Without a reminder, nobody will likely investigate further. Thanks a lot! Be good, be well Garry
