Colour picker sees all colours as black?

Hello, I am trying to use Scar with a game other than runescape, Scar works fine when this game isnt open, however when the game is open and I try to select a colour all it sees is black... So im thinking this is why my script doesn't work.

Have any of you experienced this problem before and/or know away around it?

Is it possible for Scar to see if an image is in a certain posistion rather than a colour?

Thanks guys

 

Drag the crosshair onto the game.

 

Its a full screen game that closes it self if you CTRL + ESC it so i cant

 

Then you can't use SCAR with that game.
