Error message "DEBUGloadEditorError EditorTab is not defined"

Hi, I have been making some edits in Writer offline. If I shut down Chrome and then come back to the page I was working on later, my edits are gone and I get the error message: " DEBUGloadEditorError EditorTab is not defined"

Any recommendations on what to do?

(Google Chrome 6.0.472.63 on Windows 7 32-bit.)
