Tom,
as you say, the MacBook Air is "hardly the fastest Mac around". That's one
way of putting it.
If this is a recent install of Xcode 3.2.3, it may be installing
documentation updates in the background. Try opening the Activity window and
clicking the giant red dot beside that task. That helped me out yesterday,
with a fresh install on one of the new MacMinis.
I don't know how to get Xcode to start the documentation download again.
Stuart
