- Well, you could make it a text app, and have it force its session to
- the foreground. But that may suspend some apps, especially DOS ones.
-
- I think there is a video IOCTL you can send which will just turn off
- the screen. Perhaps by setting all the palette registers to zero.
- This might work.

- Use start, not detach. Your screen blanker generaes output, and I
- don't think detach will work with such a program. If you app is a
- text-mode app, it will get a window, which can be hidden. If it's a
- PM app, it will not show any output until you create windows, so it
- can run hidden if you want.
