Eye-dropper only show white colors

I just upgraded my windows 8.1 to 10 and has begun to get the following problem: when I try to create a new color palette using a sample bitmap, the eyedropper tool dont select the color, but instead only give me white colors.

This didn’t happen before and now it started to occur in all my others scenes, even when I try to pick the color from bitmap o vector images, any ideas? It’s slowing my pipeline production

We have the same problem. I really liked the feature of dragging the colour picker then releasing to pick whatever color is available on screen. I hope someone has a fix for this. For now I’m just using the touch feature of my companion2 to do the deed. mouse and pen doesn’t work for me…so far, using finger does. :S
