I have a quantity of Mathematica 2.2 notebooks that I developed on a
Mac.  I now have Mathematica 3.0 on a Wintel machine (Windows 95), and
have been having trouble converting the old files. I have several

     1. What triggers the dialog about converting a pre-3.0 notebook,
        as opposed to Mathematica simply opening the text form with all
        the formatting information?  It seems to have something to do
        with Windows file extensions, but I can't find an approach
        that works consistently.

     2. When, by Monte Carlo methods (monkeys at a keyboard), I am able
        to get MMA 3.0 to execute its dialog to "convert" a notebook, it
        renders the notebook useless. The primary problem is that the
        notebooks contain Format expressions for some of the more complex
        data structures.  In MMA 2.2 these expressions were applied
        just before output was presented to the user.  The 2.2-3.0
        converter seems to have applied the Format statements to the
        notebook itself, then thrown the Format statements away.  This
        destroys my function libraries.

     3. In my function libraries, I have extensive (*..*)-delimited
        documentation at the beginning of cells.  This all disappears
        in the "conversion".  Looking at the text form of a notebook,
        I see that each cell starts with a (*..*)-delimited cell-style
        definition and that this definition is merged with any leading
        comments. It seems that the converter throws the entire comment
        block away, even if it contains more than just MMA-generated

     4. I do have access to a Mac MMA 3.0, but not easily.  Must I do
        the conversion from 2.2 to 3.0 on a Mac before moving the
        notebooks to Windows?
