Gerry, Many thanks for your prompt input. There are a pair of triangles bellow each bellow in window, that seem "as if" they can be used for fine bellow volume adjustments. Nothing happens when I click with our version of 2.0 (with pack 1.39). Do these triangles work with service pack 1.42? I would appreciate if anyone can tell.
