Summary: For security purposes, I use long, random passwords that are different for each site, and I store them in my keychain. The Xcode doc set subscriptions in the documentation window require your ADC username and password. However, when I tried to subscribe to the Apple docsets, I couldn't paste my ADC password copied from Keychain Access into the password field. The password field wouldn't accept a paste. Steps to Reproduce: 1. Clean install Mac OS X 10.5.5. 2. Clean install Xcode 3.1.1. 3. Launch Xcode. 4. Open Documentation window. 5. Subscribe to Core Library docset. 6. Enter ADC username in username field. 7. Launch Keychain Access. 8. Copy ADC password to pasteboard. 9. Switch back to Xcode. 10. Paste password in the password field. Expected Results: The password is pasted in the password field. Actual Results: The password cannot be pasted. Regression: No regression testing done. Notes: The password was definitely on the pasteboard. I could paste it into TextEdit, for example. If the inability to paste is some kind of misguided security precaution, it doesn't work, because (1) it discourages the use of long, random, secure passwords, (2) is discourages use of the keychain, (3) my password was already on the pasteboard.
