I guess this is either one of the Hassy's quirkiness, or my misunderstanding of how to use it properly. After I removed and reattached the winding crank, the moving blinds are partially lifter. The camera won't fire. Both film advanced and shutter status indicators show the same color: white. Fortunately, the shutter button is not jammed. Yesterday I encountered the similar problem, and somehow by trying to cock the shutter, both blinds went down. Well now it doesn't work. What to do, then?
