	Got a problem:  I'm viewing Gifs on a Mac IIsi and it seems
(quite mysteriously) that the more I look at a Gif (the more _times_)
the worse the picture quality gets.  Specifically, the dark colors
run and even tones become spotty.  I don't appreceiate my prized images
deteriorating over time (isn't that why we use digital images?)

	I mainly use QuickGif, but also Photoshop.  Both seem to kill
by images.  

	Any suggestions / similar findings?

	Could this have anything to do with GIF87 / GIF89

	BTW, what is the difference?  Do QuickGif and Giffer both read
both?

				Thanks for any ideas.
