What is required, or what is one to be aware of when doing fullscreen work, such as with a slide show application, or game, and hiding the dock, returning it, and such? Is the case that OSX now hides it automatically when it sees a big full screen window going up? Or just when it sees direct drawing to the screen going on? Is there a particular technote somewhere I can be pointed to? I searched on Google, and Developer connection for "Hiding the Doc"k, and nothing of same phrase popped up at all. I don't get that at all. Seems like it would be a FAQ. Is this Google's Law? Searching for intuitive phrases returns nothing, ever? :) ( I used "Hiding the Dock OS X" and "Hiding the Dock OSX" in Google, "Hiding the Dock" when doing Apple searches in Dev Connection. Situation exactly: Slide show application, I put up a full size window...I need the dock to go away (if it won't automatically) and return it when done, if it was showing. Robert Covington
