    According to this link, it seems that the -v argument (and more) is broken on Windows. If you follow the bug link on the site, it seems there is a workaround. I quote the comment:

    Workaround (works with Firefox,
    Thunderbird, and, I suppose, other
    programs too):

    <program-name> -h | more

    The bug happens because, without
    redirection, the program releases its
    stdout before handling the -help
    parameter. With redirection, stdout is
    not released and you can see the
    output.

    So for example for Firefox:

    C:\Program Files (x86)\Mozilla Firefox>firefox -v | more
Mozilla Firefox 3.6.13, Copyright (c) 1998 - 2010 mozilla.org

    It works for me at least. Without | more I get nothing printed. On Linux it works with or without the piping.
