Wynn is in Latin Extended-B, O1BF (7th row, 4th column in the Character Palette).

I haven't downloaded the "test drive" of Office 2004 [[1]] and so I can't tell for certain, but might it be that you haven't specified Junicode in the font menu in the Character Palette? The runes display fine there when I do, but they show up as boxes if the palette is set at a font that doesn't include those glyphs. I'm running Mac OS 10.2.8, which may or may not make a difference.
They also seem to work fine in TextEdit and Mellel [[2]].
What a lovely and useful font!
