Help needed with in situ hybridisation

Is there anyone who has been doing in situ hybridisation with the
instruction from Wisden and Morris's "In Situ Hybridisation Protocols for
the Brain", chapter one: ISH with synthetic oligonucleotide probes ?

I tried it once, but I ran into some problems:

1) The exposure time was pretty long, 3-4 weeks. I've heard that
proteinase K -treatment would help, anyone tried that ?

2) There was pretty much non-specific background. Is that just because of
the long exposure time or should I use acetic anhydride and chloroform
treatment ?

I used uninduced and unfixed brain and 45-mer c-fos probe.

I would be very thankful for any advice,
