We are using maps that have thousands of topicrefs. When we attempt to open the publication using the Publication Manager client tool, it either takes a very long time to finally open the included map or the application crashes. When we try to change the version of the included map OR change the version of topics referenced in the map, it also will either take a VERY long time or the application crashes. Is there another way to change the versions used in a publication? When opening the map in oXygen, it just shows the main GUID, not the version.
