Question. .
Will Gimp 1.1.24 work with gtk+ 1.3.0? I am working on Gimp for BeOS

up when running noninteractively, which was messing up my scripts.
It was written against 1.1.23 and 3.0.2 of gif.c in plug-ins/common/.

All users of the GhostScript stp driver should upgrade, due to a
critical bug that causes an infinite loop to occur with some
combinations of printer choice, compiler used, and possibly other
