[Dx4win] QSO Window Maximum Size DX4Win latest edition.

[w6rll at yahoo.com]

 When I use the F5 key to open up the largest  possible size for the QSO window I see a matrix:
                  DXCC  WAZ  WAS  ETC  Mixed  Band  Mode
I have forgotten what the matrix fields signify.
All my fields are filled  with "--".
I have checked "Help" but have found nothing.
Whatever this feature is, I have never used it and maybe I would like to do so.
Thanks and 73 de Joe, W6RLL.
