The popup blocker closes windows that may open during the data discovery process. For example a dialog box is sometimes displayed when indexing ESRI Map documents. While this is helpful for users running ArcGIS on the desktop it’s not good in a server environment. Considering that there aren’t any configuration settings to block these windows we’ve added a popup blocker to eliminate them. It’s possible to turn the blocker on or off and to also view the log file for information on windows that were dismissed.
