                                                       Nov 9, 1993

  Known Bugs:

  1.  Occasional re-paint problems (seeing the original connection
      messages) after something has overlayed the window.  Pressing
      any key usually corrects the problem (I think).

  2.  Occasional application looping when tab key or cursor arrow
      keys are pressed.  I haven't been able to isolate the problem.

  3.  Host data is not displayed when using "trace ?r" in VM exec's.

  4.  Will Johnson of Purdue reports problems when using PF8 keys in
      VMBACKUP menus to scroll forward in a list.

  5.  The cursor occassionally disappears.  This is very sporadic.
      The cursor re-appears when changing windows applications or
      when the enter key is pressed.

  6.  There are problems connecting to mainframes running INTERKINK's
      SNS/TCP.  Version 2.0c may have corrected some of these problems.

  7.  Dave Juraschek of George Mason University reports screen paint
      problems when running TSO application SDSF.

  Version 1.1d Changes:                      Nov 1, 1993

  1.  Changed 25th line to be a status line.  It will indicate INSERT

  Version 2.0a Changes:                      Nov 3, 1993

  1.  Changed name of the .INI file from WINSOCK.INI to QWS3270.INI.
      This file with its default settings will be shipped with product.
      New options will be added to this file as they are developed.
      It must reside in the WINDOWS directory.

  2.  Allow port number to be changed.  It defaults to the value found
      in the QWS3270.INI file or to 23.  The default in the qws3270.ini
      file can be changed via the setup dialog.

  3.  Allow colours to be changed.  It defaults to the value found
      in the QWS3270.INI file or to values predefined in the program.
      The default colours can be changed via the setup dialog.

  4.  Corrected "System error, Divide by zero or overflow error" when
      a key is pressed before a connection has been made.


  Version 2.0b Changes:                      Nov 4, 1993

  1.  Added ability to specify a DOS envrionment variable to that
      the qws3270.ini file does not have to be in the WINDOWS directory.
      SET QWS3270=c:\directory

  2.  Removed need for the SERVICES and PROTOCOL files.  The application
      no longer users calls that require these files.

  3.  Corrected screen paint problem where typed characters were
      shifted left by 1 screen unit.


  Version 2.0c Changes:                      Nov 8, 1993

  1.  Attempting to correct connect problems to mainframes that are
      running INTERLINK's SNS/TCP version 3.2.2 (8/26/91). The fix
      works for this version but does not seem to work for other
      versions.

  2.  Changed SETUP menu item PORT to DEFAULTS.  This now allows
      the host name and the port number defaults to be entered.

  3.  Added option to turn off message beeps.  This can be set
      dynamically using the setup menu item.

  4.  Added auto connect option.  When this option is set to yes, the
      application automatically connects to the default host using the
      default port.


  Version 2.1a Changes:                      Nov 9, 1993

  1.  Added ability to specify host name and port number to be input
      via the command line.  The application automatically connects
      host using the specified port number.

  2.  Corrected problems associated with the setup colour dialog.

  3.  Added ability to copy screen contents to printer or clipboard.
