Brian, YES, i have experienced that same sort of trouble, several times actually! Overtime, some VERY DRY films for some reason lose the stripe.....I think it mUST have something to do with the adhensive used. I have a picolo film ...digest from the 70's which lost the first 3 minutes of the stripe...but, stayed intact, simply "fell" off the film. I repasted it...but what a terrible task. Another film, I noticed black "dirt" on a film, then realized the track has/is falling off. After cleaning, it simply removed what was left. I beleive it has to do with having the film become DRY and BRITTLE over time, since, the film which had this happen to, were in that same condition. ANY THOUGHTS?

Something like this happened to me a couple of years ago-
I had a 400 foot reel of ads and trailers that had gotten wet (from water). It had actually been wet for about a week when I discovered it, so I quickly thought that maybe if I clean it, it will be O.K.
Using a film cleaner that I had used plenty of times with no problems, I cleaned the film. Upon projecting, I noticed that the picture was fine, but the volume kept dipping out and back.
Upon close examination of the film, I noticed that parts of the sound stripe were coming off. Not as a whole strip, but like it was disolving.
I came to the conclusion that the mixture of water and the chemical used for film cleaning caused the reaction that damaged the track.
Other than this incident, I have not had any problems with film cleaner damaging the track.
