This fall when John Deere came out with JD Office I felt that they had finally integrated their programs between Field Doc and Yield Mapping; only to have another major glitch occur....It seems, if one is running Windows 2000 or Windows XP, and one formats the data card with those programs, the card will become unusable! One must find a machine running Windows 98 in order for the mobile processor in the combine to recognize the card and retrieve data. Now realize, that Microsoft no longer supports Windows 98 so to have to format a card with a dead opeating system is not only stupid, its inexcusable!!! 1 step forward, 2 backwards..
