Finally, what seems to be vastly improved functionality for CSpinButtonCtrl and CEdit buddies. Seems also to work in wave export dialog and DPCM dialog where text is used instead of numerics.
Seems like every CSpinButtonCtrl but the key step works nearly flawlessly.  DPCM count has a glitch going between 'off' and 0.  Otherwise, the CSpinButtonCtrl behavior is much improved.
