Bruce,

Would you mind Emailing me one of the offending images to look at? I *might*
be able to quickly put together a Mira file import plugin that would
translate the bad keywords (when you save the image, the fixed keywordds
save with it). Not a promise, because I don't know what is invovled
yet---but I wouldn't mind checking it out.
