Locians, Here is an article about the porting of GTK to the BeOS. This is of interest to us because the plan for Loci is to develop under Python-GTK and wait for GTK to migrate to non-UNIX systems. I have been confident that the great interest in GTK will solve much of the portability issue for us. http://www.benews.com/story/?ID=623 Jeff -- J.W.
