Thumbnail for audio file (using video player)

We are using a video player to steam audio files, and we would like to have a thumbnail that persists through the playing of the video. We currently can set a thumbnail, and the thumbnail will persist while the video is played unless someone uses the scrub bar to move to a different time in the file. Once the scrub bar has been used, the thumbnail image disappears and will not reappear. Can the thumbnail persist, even if someone scrubs to a new time? Is this functionality possible?

There was a bug in the player that caused the thumbnail to disappear when seeking an audio track.
This bug was fixed in the latest release: 2.42. Please use that version.
Also, please make sure you set the Flashvar: EmbedPlayer.KeepPoster to true.
