I don't know if is a bug of Sigil or something I'm doing wrong. The following is a picture of my "Book Browser View" BEFORE building an Index:
As you can see, the order of the files is: Cover, Sinopsis, Titulo, Dedicatoria, TDC, Introduccion, Prefacio, Seccion_01, etc.
And this is the picture (of my "Book Browser View") AFTER building the Index:
Now the order of the files is: Dedicatoria, Introduccion, Prefacio, Sinopsis, Título, cover, TdC, Seccion_01, etc.
The question is: why is that happening? That is happening even with a blank index.
EDIT: I'm using Sigil 0.9.10 and Windows 7 x64.
