My computer set up has dual monitors, a Mac Pro. When I am working with PhotoShop, CS-6 under OSX 10.9.5 the tool windows such as Layers and Characters keep moving back to the same screen the working surface is on. This is very irritating, and I have to constantly move the tool windows about to work beneath them. Is there a way to set PS so that they stay put? If so, I haven't been able to find one.
