On the Tools menu, click Project Options, navigate to the Processing Options tab and click the Advanced Options button. Click on the "Fetch Data For All Blocks" button to open a list of .dbdoc project files which can have blocks with no source display live data.
Check the boxes beside specific .dbdoc files to display live data that has no source, then choose Apply Changes. (If the unchecked .dbdoc files are currently open in Hyperview, you will be reminded to close them.)
