Every time the search criteria changes such as an additional device to track or changing the amount of points to display, you must do a manual screen refresh. This allows you do do multiple actions at once without the map refreshing on every change.

To ensure you start tracking all your checked devices, you can refresh your data by:

• Clicking the Refresh data points link in the Search options area
• Re-clicking on a device name link by hovering over a checked name until a hand link appears and clicking
• Clicking the Refresh data points icon

You must have at least one device selected by clicking their checkbox before any data points will be plotted.
