Symptom
If you paste before the Clipboard has synchronized from the Classic environment to the Mac OS X environment, the pasted data may not be what is expected.
Solution
Update to Mac OS X 10.1.2 or later. Use the Software Update pane in System Preferences, or download the update from Apple Software Downloads (
http://www.apple.com/swupdates/).
