The DSI button provides the user access to the About, Help, and License Manager options. The About screen informs the user of the release date for the current version of CVLGrid. The Help menu provides context sensitive user guidance. For the most up-to-date guidance the user should refer to the Knowledge Base.In some cases the user settings for screen resolution can cause the DSI button to be hidden. In this case use the F1 button to access Help, and use the F3 button to display the License Manager.
