When I go through the hammer configuration setup and using their help guide, it gets to the compile setup and I can't click the icon you stated because it is greyed out and hitting F9 takes me to a screen that is asking if I want to save at that point. Initially when I first get into the hammer editor I go to the options at the top left part of the screen and that takes me to a screen that displays general, 2d, 3d, textures, game configurations, and build programs and using their guide the last thing I have to do is do the compile setup....cannot find that.....Frank
