Probably. There are several parts of StockCharts that use popup windows for legitimate, non-advertising reasons. Popup-blocking software will prevent you from using many of the important features of our site. Things that may stop working due to popup blockers include: scan results, saving favorites, annotating favorites, and certain support pages. You'll need to configure any popup blockers you have to allow popups from “stockcharts.com”.
Note: Older computers often have several programs that contain popup-blocking software. Programs such as web browsers, browser toolbar add-ins, and Internet privacy filters can contain popup blockers. Make sure that you configure all of those programs to allow popups from “stockcharts.com”.
