        1.9 consists of the following modifications:
           Bug fixes.
           Static Display List is no longer available for AutoCAD 11 and 12.

        resolutions are available for renderings.

Known Limitations:
ADI 4.2:
1.      AutoCAD 11, 12 - With a combination of dual screen mode and shell edit,
        ACAD screen is corrupted.   The problem occurs in all resolutions under
        AutoCAD 11, and only 640x480x8 in AutoCAD 12.  Use the command
        "REINIT S" to correct the display (only in ACAD 12).

2.      AutoCAD 11, 12 - After using the Birdseye, a non-transparent Aquila
        command may behave as a transparent command in the command stack.
        Pressing the space bar in this condition causes the command prior
        to the last one to appear.

3.      AutoCAD 12 AVE - REPLAY IMAGE to a non-black screen will result in
        inaccurate colors in the replayed image.

4.      AutoCAD 12 AVE - When configured for 256 colors and a 256-color
        drawing is saved and reloaded with AVE Preferences/Color Map set to
        Best Map/Fold, the display of drawing colors may appear to be
        limited to 8 colors.

5.      AutoShade 2.1 - Dual monitor configuration is not supported.

6.      AutoShade 2.1 - Changing Settings/Background to a non-black background
        color will not display the background color during renderings.  This
        occurs for any resolution with more than 256-colors.

7.      AutoCAD 12 AVE - Extra lines or rectangles may be displayed under full
        screen renderings with more than 256 colors.

8.      AutoCAD 12 - Modelspace viewport boundary may partially disappear
        after entering AME authorization screen if Flip-screen is disabled.
        Workaround:  Type Redrawall.

9.      AutoCAD 11, 12 - With 1/2M boards and a display resolution of
        640x480x256 colors, some pixel debris may appear on the right side
        of the screen after selecting from pulldown menus.
        Workaround:  Flip to the textscreen and return to graphics screen.
        If Flip-screen is enabled, shell out to textscreen and return.

10.     AutoCAD 12 AVE - Rendering to a viewport may corrupt the right edge
        of the active viewport's boundary line.

Generic CAD:
1.      Display of image placement cursor is incorrect when loading one
        drawing over another.

VersaCAD 7.0:
1.      With dual screen mode cursor trails may appear during Viewport
        command at 4-bit resolutions.

2.      Zoom in/zoom out inaccuracies occur in selecting a displayed area.

3.      The selected object does not flash on the screen for all resolutions.

4.      The VersaCAD birds-eye command is not supported.

5.      After an initial boot to Drafting or Modeling, vertical lines are
        displayed at the bottom of the first screen.  Restarting with a warm
        boot will not reproduce the error.

1.      The Mouse Systems driver is not supported in this application.
