However I replaced it with an 8-bit version after I found the problem was with 16-bit images. I've tested emacs with the new 8-bit version, and it works correctly. [If you really want I still have the old 16-bit versions, but it looks like the issue also happens with the "fnordware.com" images, so I assume no need...] -Miles -- Do not taunt Happy Fun Ball.
