Visio2002: Visio Appears to Stop Responding When Listing Network Devices in Database Viewer

In a network diagram based on your AutoDiscovery database, when you double-click a device class in the Database Viewer to expand the group in the tree and view its contents, Microsoft Visio may appear to stop responding.

This behavior can occur when the database is very large (for example, a database that contains over 40,000 devices). When you expand sections of the database that contain a very large number of devices, it takes time for Visio to process and list the devices in the Database Viewer. The mouse pointer may or may not change to an hourglass icon during this operation.

To work around this issue, do either of the following:
