When you are working in Excel, you can ask Openbox to keep track of any changes, so they can be written back to the Openbox window. This means that each changed row will be marked with green highlighting in column A.

If you don’t want this marking, you can remove it, and prevent any more marks appearing, by taking these steps.

1. In Excel click the “Openbox” tab in the Ribbon
2. Make sure that “Auto mark” is not checked
3. Click the “Unmark all changes” button
4. Click “Yes” when asked if you are sure

All the green markings will be removed.
