By design Second Copy does not show the Preview window in the following cases: (whether it is during the restore or normal copy operation)

1. If there is nothing to copy.  That means no files have changed and there is no need to copy them.  In this case, since Second Copy is designed to work non-intrusively, it does not show a preview window.

2. If the user has selected "Compress" or "Exact Compress" option on the "How?" tab, the preview is not displayed.  By the way, for Compress and Exact Compress modes, there is no "Show preview ... " box on the "Finish" tab.

3. And the obvious situation when the option "Show preview before running profile" is not checked on the "Finish" tab.
