BASIC problem in Spectaculator

I have a piece of music written in +3 BASIC in spectaculator (using FOR LET, PLAY and NEXT) and when it auto loads (because of save "tune" LINE 10) it doesn't start from the beginning of the song. It actually starts from a part of the song that is not it's own $ - half way through a $ at the end of the tune! Then, when I run the same file after it has loaded and auto-played it plays perfectly.

No other emulator that I play the music in does this upon auto-run on first load. A real +3 doesn't behave like this either - it plays it correctly.

Any ideas what the problem might be in Spectaculator?

Thanks for any help,

Matalog.
