    • Support for ODBC databases was added.
    • Mark Selected rows was added. Rows may be selected by ctrl_click or Shift_click.
    • Current Training/Testing range now shows on most screens.
    • Predicted, Actual and Difference now show during mouse moves on the backprop scatter graph.
    • The Advanced Setup screen may now be printed, along with most others.
    • File Import now accepts both .csv and .txt extensions.

  • NeuNet Pro Version 2.2
    • NNP22.EXE was released on November 30, 1999.
    • A graduated purchase plan was implemented, with free level-one registration.
    • Mark, Unmark, Toggle All Rows now apply to current view only.
    • Minor bug fixes:
      • Program crashes if missing data causes no useable training rows.
      • Intermittent "OverFlow Error" on SFAM training.
      • Bottom status bas was sometimes holding stale messages
