Thanks for your quick reply and apologies for the inaccurate phrasing of my problem. When using the eyedropper, with the Sampling Ring turned on, there are a number of gray to white dots that spin on and off when I click and hold down my mouse, similar to when Windows is starting up or closing down. The eyedropper works fine inside Photoshop and all I need to do is click once, and the targeted color is immediately registered. However, I can no longer drag the eyedropper tool outside of Photoshop, for instance, to sample a color from a web page. Someone mentioned above this might be an NVIDIA driver issue. I'm using a GeForce GTX 980M/PCIe/SSE2 processor with a Microsoft Surface Studio Pro. I do want to mention I'm left handed, so my mouse is configured with the left and right buttons reversed, so, to drag the eye dropper out of Photoshop to sample a web page I am clicking and holding down the left mouse button as I drag, but it is not sampling colors outside of Photoshop. Appreciate you expert assistance/guidance, JJMack
