swatch thumbnail eyedropper not working

I have the problem at the moment where the eyedropper tool for making the swatch thumbnails isn't working at all. When I try to use it all that happens is that my mouse icon will change into the eyedropper, and that's it, it will not pick up any color or interact with with anything at all. in fact the mouse an only change back if I right click on the emtpy swatch a few times and spawn another error. I don't know if they are connected or not.

This is the error I get if I click on the swatch box with the brocken eyedropper-
