SkyMap screen capture

    Hi All,
    Wanted to chime in on this SkyMap Windows screen capture business.
    As Richard Crisp indicated, the PrintScreen/SysRq key is what I've
    always used, and it works fine for Windows 95 or Windows 98.
    Unfortunately, I'm now running Windows 2000 NT and
    it most definitely does NOT work there.  Nor does using
    Alt-Print-Screen.  (When you use the latter and then attempt to
    use Ctrl-V to paste in Windows, you get the error message:
    "Unable to get the data from the clipboard."
    If it doesn't work with Windows 2000 NT, it probably doesn't work
    with XP either.  So Kevin, it's not your fault that you haven't
    been able to get it to work.  It's the damn Windows "upgrade"
    that isn't backward compatible.
    I decided to take Michael diLorenzo's suggestion and downloaded
    Snagit from  While Snagit will work with an
    ordinary DOS window in text mode (e.g. a SkyMap menu screen),
    once SkyMap is in graphics mode with a star map plotted, the
    screen capture no longer works.  All you get is a white image.
    I've tried all the obvious alternative SnagIt settings, but
    none work with a DOS graphics screen when used in conjunction
    with Windows 2000 NT.
    Since capturing screen images is such a basic capability that I
    cannot do without, and Microsoft has shown no consistency between
    operating systems on this feature, I will probably just write a
    BIOS routine to do it within SkyMap and send the output to a
    .BMP file.  (When it comes to Microsoft, I increasingly find
    myself asking the question, "Do I have to do EVERYTHING myself???"
    I see the day coming when I will have to write the code just to
    instruct the hardware how to make the electron gun raster-scan
    to produce color images...)  --Rob
