Looking for suggestions on the cause of wavy sections, so bad that we are
unable to focus under high power.  This has happen out of the blue without
changing any procedures.  I am cutting all skin, some look good,  but this
problem seems to affect the staining ex. muddy appearing, poor contrast and
understaining.  All temps. are with norm. except of a paraffin bath on
processor is 64 C. Sections have been good 2 days a week then progressively
get worse.

Thank you
