Tonight I inadvertantly changed the name of a directory holding a project while the project was open in XCode.
This caused Xcode to crash.
When I restarted XCode it crashed again because it tried to re-open the project on startup.
Once I put the directory name back to what it was, and restarted xcode, things looked fine until I tried to add a file to a project.
The file chooser comes up as normal, but when I click on a directory to navigate to the desired file, instead of opening the directory in the chooser, it just adds the directory to the xcode project.
Thinking the crash probably corrupted some xcode system file, I removed and reinstalled Xcode. That did not help.
To verify that it was a problem was user related, I created a new user account and ran Xcode there, and it worked fine, I could navigate directories as normal in the file chooser.
Has anyone encounered similar navigation problems, and does anyone have a suggestion how I can clear things up for the problem user account?
