My Photoshop CS 6 Color Range Selector stopped working on my iMac It opens but will not allow me to select anything with the dropper. The buttons all operate but the selection never happens. I have the following selected: Sampled Colors, Localized Color Clusters (I have also tried without this selected) image(display) and selection preview= none. The image is 8 bit but I have tried 16 bit as well. No selection appears no matter how the fuzziness and range are changed. If I enter a warning appears: No pixels are more than 50% selected. The selection edges will not be visible. I have reinstalled and restarted to no avail. This tool has worked before without a problem. Any ideas?
I have seen this happen when the wrong layer is targeted. If your layer is a shape layer or type layer, no pixels will be selected.
