Normally Phex should download in 16k junks and increase the size as soon as it got its first segment completed.

The first segment should also get larger as the time goes, because segments get merged, but as of the newest code, Phex no longer always takes the first segments first, but the rarest first.

Normally it should still get the whole file (do it faster, even) as soon as all segment got merged, and it should download mp3-files from beginning to end.

As teh files get completed they should be moved to another folder, maybe the bug lies there (for me it works flawless, so I can't judge that).
