Is anyone else having problems with polaroid film?

Recently, I have been seeing a number of my polaroid photos coming out strange. It appears the gel is not evenly distributed across the film and large portions of the photo end up white (undeveloped).

I attributed this to the dry desert air and poor storage conditions, however I just received a comment from an east coast friend and he is seing similar problems.

YES*** For about 3 months we've been having exactly this problem - so its clearly nothing to do with dry air. In fact, I have got so sick of it that I am about to send back some sample films to Polaroid - maybe I (/you?) should ship the entire batch back.

The worst (recent) examples have COMPLETELY blank films

Thank you for all the replies (email and news).

I should have mentioned that this problem is occurring wiyh three different cassettes, one of which is very new. These are the manual "cameras" which came with the Syntex P21 and the Nonius CAD4. We have seen this problem over several different lot numbers of film. All expiration dates have indicated that the film is not "expired".

p.s. sorry about the "down 18" subject title, I guess I hit one of my predefined news reader function keys, when I should have entered the subject!
