Hmmm, just came up with a theory. If you look at my picture (three posts above), you'll see a big bead of Vulkem along the top edge of the window hinge. The theory is that this bead is actually concealing a little rain gutter, and this is causing the leak. Without the rain gutter, water runs over the top of the hinge and into the gap just below, rather than being diverted to the sides. Anyone with similar windows care to comment?
I'm going to go dig the Vulkem out of one of them on the next sunny day to find out.
