Because the code's a bit flakey in some areas, basically. (I'm allowed to say that: I'm responsible for the bulk of it). I think the real reason that Wendy flags aren't implemented particularly well is because Hugo had broken up with Wendy by the time we got around to implementing them, so it wasn't quite as important

Small note: emplode 2.00 is more stable than emplode 2.10. You'll only need emplode 2.10 if you're dealing with foreign language (non-Latin1) tags or Ogg Vorbis or FLAC.
