Collection question

I've been analyzing files in Mixvibes and notice that it clears out the Genre column.....what gives?
Second question.....those using Cross, what do you use live...the iTunes window or the collection window? Seems to me the iTunes window is easier to use....I have all my playlists at my fingertips.
