    Description: mfwFocus is NULL when window callback function for MfwWinResume
    is invoked in winDelete.
    Solution: After deleting a window and all its components, set mfwFocus to
    the previous window, before calling window callback function for
    MfwWinResume.

	allocate/ deallocate mbndata
	Solution: removed the unused varialbe mfw_twh_strlen
