No display after full screen command prompt exit

[Guest]

If I open a dos window (command prompt) and go full screen by pressing
alt-enter and then exit by typing 'exit'/enter, my display goes blank. The
same think happens if I press alt-enter a second time. After this I can
toggle using alt-enter between a full screen dos window and a blank display.
The keyboard seems to be fully functional. Knowing the keystrokes, I can
shutdown or restart windows, but I cannot seem to restore my desktop without
doing so. Also if I let the screen saver activate I seem to be in a
permanent blank screen. Any suggestions. Thank you.

Try lowering graphics hardware acceleration slide. You can lower
graphics hardware acceleration in Display Properties, Settings tab,
Advanced button, Troubleshooting tab. If this helps, you probably need
a different graphics card or drivers.

Thanks but that didn't work. I moved the slide to none with no change. Any
other thoughts? The adapter is listed as an Intel 82845G/GL/GE/PE/GV Grapics
Controller. The driver version is 6.14.10.3943 dated 11/2/2004. "Driver
Detective" did not find any later driver.

Try Intel.

I did find a later driver on Intel's site, which I installed. It seems to be
working now. "Driver Detective" doesn't seem to be quite up to date. Thanks.

i tried pressing alt+enter to enlarge the dos window.but it's a bit too
large(streched vertically).i cant see the first two lines(so the 3rd line
appears as the 1st line).

I tried on another computer.but,heh , the font,graphics, cursor etc are a
bit too small.(rest of the screen is black.hey but it still is a 640x480
graphic screen! & ?).
os is windows xp(both pcs).

How do i get the window to be of the right size?
Note: my knowledge about dos & windows is "too less".so iam not looking 4
complex solutions.

2nd question:
how do i run a program in the background?ie the console window must not be
visible.i made a program (a maze solver program) using the old turbo c++.the
program is too slow(probably due to bad algorithm).the program should be able
to recieve keystrokes even when "hidden" so that i can "unhide" the console
window whenever needed(i hav used c++ commands such as cin,bioskey()).is it
possible?its better, if i can do it by system calls.

That's all.
Thanks(in advance)
