I had installed Xcode 4.1 on Lion and recently I saw the update for Xcode in the appstore. It was to update my current Xcode 4.1 to 4.2 with iOS5 SDK. It's around 1.8 GB of download and I did update it through app store. But at the end of the update, the update download restarted and I let it happen. But even after second download it restarted the download and started the updates downlad for third time.
I'm sure there is something wrong with something; either with OS or App Store or Xcode. Is anybody facing similar issue?
