I have $Version = "4.0 for Microsoft Windows (April 21, 1999)".

I just created doodles using both Corel Photo-Paint 7.467 and PaintShop Pro
4.12 (shareware from http://www.jasc.com/pspdl.html), and then saved them as
a TIF files. These both imported OK into Mathematica using
Import["name.ext"], and then displayed correctly using Show.

So, if I had a TIF that wasn't quite the right format (as far as Mathematica
was concerned), I would try to read it into one of these packages (which
might be less fussy than Mathematica), and then save it back to disk again
in what would hopefully be the right format.
