      Description

      From Mike Richardsson:
      We noticed in our application that the problem is not fixed. We have more levels of nested split panes than the original example...

      Here is the original example modified to show this issue still requires some work. Notice if you press the Adjust button the dividers are being set on each occasion. The problem seems to occur when we add tables to each split pane (which our application does)

      package application;
