Texture Paint - Quick Edit bug

I am using Blender 2.67 on OSX 10.8.3.

I have tried to use the Quick Edit tool in the Texture Paint Tools Palette with Photoshop but nothing happens after I save the png file when I click the Apply button. I am in Texture Paint mode with Texture Preview on.

Do I need to unwrap the mesh to view first?

thanks for any suggestions

Whoops! Forgot to unwrap to view and add a map first!
Works fine :o
