The Sharing tab of the Options dialog box contains settings that affect how you use Microsoft Office Live SharedView.
Always Show Preview
Select the Always Show Preview check box to automatically open the preview window when you share an application or the desktop. If the check box is cleared, you can manually open the preview window by clicking View what other see on the Share screen. By default, the Always Show Preview check box is cleared.
Microsoft Office Word Options
Select the Use Track Changes option to use revision tracking for any Word document that you share. By default, the option is selected.
For tracked changes, you can use the Word revision tracking options configured in Word on the host computer for all revisions, or you can select the Use SharedView authors and colors check box to override the Word settings. This causes each participant to have a separate color, which makes it possible to identify who made each change. By default, Use SharedView authors and colors check box is selected
