Hi Netters,
    We have recently had a sporatic incidence of a cloudy, white film on the
back side only of thin prep and medical gyn slides. It  does not  seem to
interefere with reading the slide and it can only be removed by scraping it
off with a razor knife. It only happens once in a while, usually when the
reagents are fresh. Any ideas as to what is going on? Thank you.  Maureen
