I just sent this question to Matthias Clasen, who increased that number from 4096 back in 2002. It seems that a pixbuf sets an arbitrary size limit on how much data can be loaded in a single chunk. The real question is whether that limit is intentional or merely a bug. Meanwhile, Brian Downing posted a patch to the pan bugreport: http://bugzilla.gnome.org/attachment.cgi?id=96917&action=view His patch explicitly limits the amount of data Pan sends in one chunk, and this is the correct fix at least until we know if this size problem is a gdk bug or not. _______________________________________________ Pan-users mailing list Pan-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/pan-users
