Problem: .NET web mapping applications in 9.2 don't work correctly with Internet Explorer 7
When using Microsoft Internet Explorer 7 to view Web applications created with ArcGIS Server Manager 9.2 or the Web mapping application template inside of Visual Studio 2005, the map disappears from the page, for example, when opening the magnifier window.
This is a known issue and has been addressed in ArcGIS Server 9.2 Service Pack 1.
