Yesterday this finally happened again (this time I was winding the film) - I loaded the back correctly and closed it up but when I wound the film the counter did not catch. I wound it a second time to make sure it wasn't working, then opened up the back, closed it again and it worked as normal (now though I suppose I might not get 10 shots?). Does anyone know why this might be occurring? Exactly how does the back know there is film in it to start the counter moving? If I knew what was supposed to be happening mechanically I could see if it is something easy to fix.
