You have the option in some views to automatically update the view at an interval of your choice.
Sometimes you need to refresh the data when you want to, especially while inspecting the data.
Most views have a local refresh button, which updates the data.
The same function is found in the Tools menu, as well as an option to update all views at once:
 Tools menu 
 Refresh  
 refresh the data displayed only on the current tabbed view 
 Tools menu 
 Refresh All  
 refresh the data on all the tabbed views 
Or use the Refresh and Refresh All icons on the Tools toolbar.
