Gunn,

Ok, look on the exterior of the windows. Do you see what look like trim
pieces between the glass and the frame? There should be 4 of them running
around the inner edge of the frame. They are spring clips. Gently and
carefully pry them out with a putty knife. Try not to deform them. Once they
are out of the way you should see the glass edges embedded in glazing
compound. remove the glass and glazing compound. Clean up the frames with a
putty knife. Et c.
If this doesn't help post a few pics.

Thanks Dave

Next time I'm there I'll see if they are made as you say. At least I
have an idea what to look for now.
