By default, your Dashboard is set to automatically refresh once every minute. You may set your Dashboard to automatically refresh less frequently or to require manual reloading.
1. Click the Settings icon on the Ribbon. The Settings window will open with the General tab open by default.
2. To modify how often your Dashboard refreshes, ensure the Automatically Refresh Dashboard Assignments box is checked, and in the field below, specify how frequently you would like the Dashboard to refresh (from once every minute to once every sixty minutes).
To set your Dashboard to require manual reloading, uncheck the Automatically Refresh Dashboard Assignments box.
3. Click Save. At any time, you may click Reset to return your Dashboard to its default refresh settings.
4. Restart Perspective (log out, then log back in) to enforce any changes that you have made.
