Frank's approach of using a 3D style control sounds exciting and I'm guessing lends itself to many other functions for which it is currently difficult to provide a suitable display/interaction metaphor. However, perhaps in the short term, one possible way to disambiguate mouse click intent might be to employ alternate tools other than the standard mouse pointer - e.g. a notch tool which could allow selection and drag-and-drop within the panadapter. Maybe this approach could also be applied to other as yet undreamt of functions.
