Overall this widget works very well however there are some issues. For instance, it appear to be impossible to add the FTSE 100 index (^FTSE) - searching for it 'returns too many items. For all securities that can be added the widget is extremely useful.
The Widget itself checks for updates every five minutes. The delay time for individual exhanges is available from the "Delayed Quote Info" link that appears on the face of the Widget.
There is no paid "Real Time" subscription option for this Widget to reduce or remove the quote info delay.
Has a long delay (around 30 minutes for DOW) between desktop updates unless you sign up for a subscription for "Real Time" which will cost you @10.95 or more per month. So it is all about selling you something and not providing you with a fun informative or even useful widget.
