Are you using any EtOH in treating your tissue before you mount the
sections on slides?  
We were having a similar problem just the other week.  Our frozen
sections were coming off the
slides poly L lysine or no.  The tissue had been fixed but held in 70%
EtOH until sectioning.
Once I stopped exposing the tissues to EtOH the sections stopped coming
off the slides.
