why does the glazing around my windows keep shrinking and coming loose? I remove the old glazing first and make sure it is clean before applying the new glazing compound, but it only lasts about a year before I have to do it again?
Make sure the glazing you are using is fresh and still pliable. Old glazing is prone to the problems you describe. Very dry wood in the window frames can contribute to this. Finally, try painting over the glaze after it has cured a while; this will let it dry more slowly and evenly.
