* Added a comment about the purpose of the code in AttachedToWindow().

* Improved FrameResized(). The "diff" is actually between the new location
  of the right side (Frame().right) and the location where it probably was
  in the parent before it is resized (fMenuField->Bounds().right - 2).
  Could be that this change is wrong, or at least, not yet correct. Will
  test on a different machine.
