FAQ for Black Screen v1.16   

I press CTRL-S but I still cannot get into Black Screen Setup.

The CTRL-S key press is a very particular key press. Some users may find that they must over exaggerate the the CTRL-S key press. For Example:

Hold down the CTRL key
Tap the "S" key

You might find yourself having to tap the "S" key several times before it responds. This is due to the high level of security that Black Screen has. We assure you that you can enter setup by pressing CTRL-S.

If this still does not work please try pressing ALT-TAB once, then try it. Then press ALT-TAB again until you give focus back to Black Screen. There are some instances when Black Screen will loose focus and the keys you are pressing are actually going to the program in the background (that has keyboard focus).
