[texhax] conflict babel-makeindex

[Carlos Gómez Bermúdez]

Hi

When \usepackage[greek,english,spanish]{babel} is present, the index 
show only entries of the mainmatter, but no those of frontmatter.

If I work without babel (view the precedent line) Index show all 
entries, why?

Have you a solution?

Thanks


Carlos Gómez Bermúdez
