I've been using ps a lot lately, and everything had been working just fine, but today I opened it up and the eye dropper tool was displaying the sampling ring, and when zoomed in the pixel grid wasn't showing up. Enabling the grid in the view section didn't help for the pixel grid, and I couldn't find any other reason for it not to show up. I looked up a way to fix the eye dropper tool, but the only thing I saw was to turn on the "Show sampling ring", but thats grayed out, and I can't select it. Anyone have any ideas on how to fix this stuff?
