Thanks everyone. I had been experiencing random problems with BIAB 2015. Certainly the two I reported on the forum have now cured themselves. Or maybe it was my many checks of Preferences that helped, although I do not think I changed anything of significance from previous BIAB version settings.

Noel, I had already checked those settings several times and they were indeed set the way you said they should be. I guess the only difference with me is that I did not use the 'Save As' button because I tend to favour Menus and had been using the 'File' 'Save Song with Patches & Harmony' pull down menu item. But they both lead to the 'Assign Instruments and Harmonies to Song' box. Jareth raises an interesting point about us not needing to use that particular save method if the override settings are correct.

Jareth, I did have my 'Overrides' settings as you recommend and the only changes I had made were to tick the box for 'Strings Tracks Simple' and 'Always set loops to OFF'. The latter because of another annoying problem I had with every song repeating and being unable to stop that until I sought help on this forum.

I suppose it is possible that I had changed something in one of the screens that affected the ability to save the volumes but my many checks did not reveal anything. I should mention that I do make a lot of changes to individual tracks, such as different entries for 'Insert Section Text' to Bass, Piano, Drums, Guitar, Strings, Melody and Soloist. And a lot of swapping harmonies and inserting notation marks. I really push BIAB to create and then get decent printouts of notation for all the instruments in my band.

The other possibility is that a computer problems I am experiencing with downloading Windows updates (Specifically an IE 11 x64 bit update), could have caused a saving malfunction in BIAB. I have also experienced some random saving problems with programs such as Microsoft Word.

Anyway, BIAB is working fine right now! Now all I need to do is solve the Windows problem. I hope.

Thanks again.
