Hello, I've discovered a possible bug in the latest firmware and hope it will be of assistance. Maybe others have experienced this. If I have both text and audio files in one folder, and attempt to use the next or previous file commands (# or *) to move from a text file to an audio clip, without first setting the unit to idle mode, it consistently freezes the unit. There is no problem when moving from a text file to another text file, or from an audio file to another audio file. Hope this helps, Grant
