I unfortunately experienced the same thing last night on a new piece I had been working on. I saved it (I thought) and tried to make a .wav file of it to listen to on my MP3 player so I could determine where to go with it next. When I closed BiaB it asked if I wanted to save it. I assumed that making the .wav file made BiaB believe I had changed something. I saved without thought and went to play the piece in Soundforge where I usually convert it to mp3. There was no melody. So, I re-opened BiaB 2010 only to find the melody completely missing.

I really liked the piece and the melody maker had made a very usable melody. I hadn't been working on it long and can't really remember how all 32 bars went so reconstruction won't happen. DRAT!!!

Is this a known bug and is there a fix being done?

Disappointedly,
