Do you set the "Always use ID3v2 tags" radio button in the settings menu, and it reverts back? Let me know and I'll submit that as a bug.

Also, does the same go for the "Always reclaim" button? That is, do you set it to "Ask" or "Never reclaim", and it reverts back? If so, I'll put that one in as a bug too.

I just leave MM as my main media player. If I ever want to use something else, I just open the program and drag things into it. The only thing that bothers me is that I can't seem to get MM to NOT autoplay CDs. That one bugs me to no end.
