Often when I open Photoshop CC through Lightroom 5 no tools will be working at all. I press Z for the Zoom Tool, but nothing happens. Press O for Dodge/Burn, nothing happens. The cursor just stays visible, and this happens if I select different tool with my mouse as well. Kinda annoying when you run into this quite often. I am running Mavericks 10.9, and I got all the latest updates for my Adobe programs and the OS.
