Hi Mark,

It happened in all cases, so far. Everything I opened in 2.1 was in the directory Notation/Songs 2.1, to which I have so far remembered to copy everything in case I need to open it in 2.04 some time.

I made another directory, Notation/Songs Two and copied everything from Songs 2.1 to that. Now save as in Composer works as it always has, with the name of the piece showing in the File Name dialog.

Is the lesson: don't include digits in directory names?

all best,
mgj
