We use Mayer's Hematoxylin after new fuchsin and did have fading of both
the counterstain and chromogin usining aquamount and DAKO glycergel.  We
use DAKO's ultramount,wipe around the tissue, drop  on the ultramount
(no coverslip) dry the slides in a 60 degree oven 5-10 minutes,dip
quickly in xylene, and coverslip with a permanent mounting media. We
have been using  this method for over a year, so far no fading

Dear Mary,
We observe the same problem and never found a good solution to prevent
it! 
We keep the slides away from direct light and take pictures as quickly
as 
we can. Eventually, we lift the coverslip, rinse the section with
lukewarm 
tapwater and re-counterstain it with haematoxilin.
