Although I have turned off the automatic taking of snapshots in Zotero, I keep getting snapshots attached when I add items from Google docs results. Any clues as to how to avoid this?
Right - I have the same problem. Whenever the Chrome extension presents the "Item selector" window (as it does in Google Scholar), it saves a snapshot.
This occurs even with snapshot-saving disabled in the Zotero Connector extension (Connector Preferences > General > Save to Zotero.org > Automatically take snapshots unchecked--even though I'm working with standalone) and in the standalone app's preferences (Preferences > General > Automatically take snapshots unchecked).
This is now fixed — thanks for reporting. Your Zotero Connector should auto-update within 24 hours, or you can update manually by clicking Update Translators in the Advanced pane of the Zotero Connector preferences.
