Hi I've recently noticed an error when working in Photoshop. Sure hope i can describe it. When using the brush tool and laying down some random strokes on the far right of the canvas the colors start to change.For instance on a bright orange color the color starts to change to a slight purple when on the right Side of the canvas.

Also when i move images to this side it also messes up the colors it turn this a slight hue of purple which i really hate.

Does any body know why this is happening? Has it ever happended to you i have included a picture to illustrate my problem.Sure hope someone in the Renderosity forum can help me out with this mess.
