From a recent GAS attack (again...) I received my Lynx 14.

Shutters seems to fire ok, aperture blades look clean, no fungus, overall looks are used, but good.

However, sometimes, the film advance lever stays in the "wound" position and will not snap back. I need to unscrew the screw and fiddle around the winder a bit, then it will snap back into "normal" position.

Any ideas on how to solve this? I can't really see any consistant scenario when this happens.

Thanks and cheers from ice cold Switzerland.
