Hi, After loading a roll of film and winding to frame #1 I can't fire the shutter. The electronics seem to work OK and the display in the finder shows the "X", which you can usually only see when there is no film in the camera. So, I think the camera doesn't detect the film. I have opened the back, rewound the film and tried it again, still no good. Tried another film and had the same problem. The film transport stops properly at frame 1 though. I did press the Multiple Exposure button to get rid of the "X" and could fire the shutter, but then I couldn't advance the film (as it should be). Has anybody had a similar problem? Do you know a solution? Thanks.
