Click on a Script to populate the area to the right with details about the script itself (Summary) and additional information about the system and installed products which might be requested by your support contact if you are not receiving the required results (Details).   The Checks tab, if shown, will always be empty as that is only populated when in results mode when Quality Checks are in use.  The Content tab lists out all controls in the Script by role which is useful if you need to see how many times a specific control appears, for example.  The final tabs contain information about each TestDrive Application that was used during the recording of the Script.
