  • Screen blanks (10-15 minutes) Windows 2000

    Anyone know why a 1.6 Gigahertz Gateway machine running
    a DOS program would have the screen go blank after 10
    to 15 minutes? The user says it only happens in our
    DOS program. They use Windows 2000 and in power settings
    for the monitor they have shutdown in 666 minutes.
    We have this program running in many locations, but
    this user cannot keep the program running. Anyone
    know of any incompatibility with a DOS program running
    on Windows 2000? They switched to a PS2 port mouse
    and it fixed a screen problem.

    Gosh Mike, you certainly have some interesting situations arise!

    Is a screen-saver configured? What power settings are configured in the BIOS (DPMI, Blank, H+V only, etc) and the Windows Power Saving?

    Are there any background apps running?

    Is the app running full-screen or windowed? Is the app set for "Allow Screen Saver" (it probably shouldn't) - check that out in the Misc tab of the Properties of the shortcut to the app.

          Only that they want their money back.

            Mike --

            What happens if they leave another DOS program open, such as EDIT.COM, instead of your program?

                It also helps sometimes to tell the SHORTCUT's ADVANCED PROPERTIES pointing
                to a DOS program to "Prevent the DOS program from detecting windows".

                  Can I ask how, Otto? It seems to me that that would affect the ability of the code to detect Windows and release time-slices or set a "critical section" for timing-critical operation (such as faxing, etc).

                    Otto,
                    "Prevent DOS program from detecting windows".
                    Definitely causes problems.
                    Thanks for the suggestion, though.

                      It probably will if you are programming on that level in DOS

                      It works with some older DOS programms such as PcAnyhwere for DOS 5+
                      and others, but not all.

                      I have it set whenever I have to run my PB-DOS programmes from the
                      Windows Desktop. If my clients want programmes to write and send
                      Faxes or communicate with the Web, ect, I tell them to find somebody
                      who can write expensive and buggy Software for Windows to do it with
