Ever since I updated the Reference Library from within Xcode I ran into the following problem. When I use the Back or Forward button in the documentation window, I get an alert box telling me something like: Reference.html is a web application which was downloaded from the Internet. Are you sure you want to open it? Xcode downloaded this file on 18 February 2008 from developer.apple.com." for _every single file_ _every single time_ I click it. Also, when I click "Open" in the alert box, Xcode opens the file in OmniWeb. I tried erasing OmniWeb to get rid of the association, but Xcode tracked down a copy of OmniWeb on one of my other computers. I disconnected the network, but Xcode decided to use Safari instead of OmniWeb. The last time this happened I re-installed Xcode, thinking it was a fluke. But it's apparently systematic. How can I get Xcode to display ALL documentation files in the actual documentation window and not an external Web browser?
