Does Dashboard update when opening the report?

[bdelarosa]

I left my dashboard open over the weekend, so I closed it, then opened it and noticed the same numbers were still there. I had to click the edit Icon and click on the refresh data link.

Is this something I have to do manually every time? I ask this cause it take about 20 minutes for the data to refresh as I have millions of lines sitting out there. I know there is a refresh button on the properties window, but I don't want that thing refreshing every 5 seconds other wise it will always be refreshing.
