I've had it happen, but not in the last twenty-five years. I think I probably was mixing the stop bath a bit on the acidic side back in the seventies. It probably had something to do with the stuff I was ingesting. But I just got in the habit of the quick water rinse. I think it also adds about 5 or 10 seconds to my development time, so it has become part of the process. You know how that is Shel, one of those things you leave in place if everything else is working okay. Can't say for sure that there are any real benefits. (Aside from the fact that it keeps the stop bath fresh and allows me to reuse it in the print tray.) Paul
