  hi Carl
       Try - if you do not mind spending the money - shooting a plate 
unhypered, daylight conditions.  Develop as normal.  
        If you then have this problem still, it begins to sound like a 
problem with the batch of film.  A few more things to eliminate first, 
because if you seek to return the film, you will probally be asked these 
questions.

 -D19 is weird stuff to mix.  It just never seems to mix right if you add 
water to it, you have to add it to warm water to disolve properly.  i 
have no explaination for this, other than experience.

- I'll assue you have not left the film on the dashboard of your car for 
a hot summer afternoon, left it on top of a box of spare urainum chips, 
or stored it under an -xray machine for the past year.  :)

-When you pull the film out of the fridge or freezer, do you let it warm 
up in an airtight container?  If left to the air, water drops/bubbles can 
condensate on the film while it warms up.  I do not have my roll of tech 
pan in the fridge, but I keep it in a coll basement, witht he 
dehumidifier going.  Any colour film I hyper, once I pull it out fo the 
fridge, I put it directly into the chamber, vacmun all air out, then just 
let it warm up to room temp in the vacumn.
        I do not know if taking film directly out of a freezer and baking 
it right awy in a hypering chamber would be damaging, but I have always 
assumed it would, so I let my film warm up first.

  if all that fails, thent eh only real answer is that you have not 
sacraficed enough chicken gizzards and rum to the voodo sky gods this 
month.
   As evidence of this, I poit out that southern Ontario is only 1 inch 
away for an all time record monthly rain fall.    All of you - go forth 
and drink copious quanities of rum under the comming eclipse to appease 
the angry sky gods!
