I have a Mac, and I recently installed XCode in the Developer folder that came with OSX, etc. etc... and I would love to get started learning how to program, except the application has a strange error that won't let me do pretty much anything. If I try to open the Documentation Window or the Help Menu, an error comes up saying this:

Uncaught Exception:
*** -[PBXExtendedTableView _sizeLastColumnToFitIfNecessary]: selector not recognized [self = 0x596b5e0]

Stack Backtrace:
The stack backtrace has been logged to the console.

I have no idea what this means... but if anyone knows how I can fix it, I would very much appreciate it. Thank you. :]

What version of Mac OS X?

Not just what version of OS X, but what version of Xcode?

Well, since the version of OS X limits what version of Xcode you can run, know that lets me tell him what version of Xcode to make sure he has.
