bug report on 2.15.2 Mac OS X Intel version

[Henk Verhaar]

Not a notation bug, but an I/O issue (possibly).
This morning I installed 2.15.2 and successfully created a 
horn part for an adaptation of Fanfare for the Common Man 
(I was given F horn parts and needed them in 
E-flat, so I used the auto-transpose feature of Lilypond to 
create an Eb part. All worked fine, and I must 
have saved the source file a number of times during this 
process, since I know I created intermediate PDFs 
to check progress, and I have a PDF of the final score page 
that I will use. However, It appears that 
Lilypond has somehow removed my source file, or hid it, 
or saved it somewhere else, since I can no longer 
find the correct source file.

I'll be reverting to 2.14 in the meantime...

Cheers

Henk
