I agree with what igohigh said.  The Opaque channel in tiff and png saves kills all my potential uses for it.  The low quality of jpegs saves kills the other half of uses for me.  I don't know what the manufacturers were smoking when they green-lighted this product!  If they ever fix it to the point of use, I'll be happy to use it.
