multiple indexes

[Michael Berger]

Dear LyX users,

I am using multiple indexes (two different indexes) in my document.
The page numbers in one print blue while black in the other one.

I should add that cross references appear blue as well as the

referenced page numbers in table of contents, in nomenclature, in 
bibliographies etc.

I am using  'classicthesis-Lyx- v4.1'

Any hint as to why this happens and how it could possibly be corrected?

Thanks,

Michael
