Command prompt misbehaving

    I have a number of important, old DOS programs (circa 1986) that run
    perfectly well on XP but don't on Vista beta 2.

    The problems are :-
    1. I can't make the window full-screen, even after selecting full screen,
    it's full height but only half width.

    2. When trying to run my programs, I get the message "NTVDM has encountered
    an error".

    Can anyone help and I don't mean ditch the DOS programs and rewrite them as
    it's too much work?

    Thank you.

    I'm not sure about the full-screen issue, but, I was also getting the message
    'NTVDM has encountered an error' when I tried to run DOS commands from the
    Command Prompt.

    My problem was the antivirus software that I had installed. I was using
    avast 4.7. Once I un-installed the program, the error went away.

    Thanks Unclebub,

    I'm running Avast so I'll give it a try later when I'm back at the Vista

    According to the Avast Support forums, they (Avast) are working with
    Microsoft to address the issue.

    Do you have the same problem or are you stating that by design Vista doesn’t
    have a full-screen capability.

    If the latter is true, why does ‘Properties’ in the Command Prompt have an
    option to select ‘Full screen’?

  7. Try Alt + Enter (old shortcut to get to full-screen mode). I get a message
    saying "This system does not support
    fullscreen mode."

    Thank you Unclebub and Michael.

    I uninstalled Avast and my DOS programs are working, albeit in a
    ridiculously small window.

    There was a Microsoft fix last night so I'm going to try AVG as my AV

    Come on Microsoft, give us a fullscreen!

    The new version of Avast home edition, 4.7.871, fixes this issue.

    I can now edit files from the Command Prompt without any error.
