Control Center May Conflict With Pop-Up Blockers
Pop-up blockers, software that suppresses new web browser windows, may interfere with the Control Center or Web Mail. The PREVIEW (save) feature in the Control Center may especially be disrupted by pop-up blockers due to the way that it functions. If the PREVIEW window does not appear in the Control Center, or the Address Book window does not appear in Web Mail, make sure that there aren't any pop-up blockers interfering. The Control Center save function for preview may not properly save the settings with the pop-up blocker stopping this.
