I have just found out (from EricLaw's IEInternals) that .NET Framework XAML Browser Applications (XBAPs) are now prevented from loading from the Internet Zone in IE9. When visiting an Internet site that utilizes an XBAP, an error message is shown, indicating that the application type has been disabled. The reason is that “(...) they are not commonly used on the Internet – Microsoft’s crawls of the top 100,000 websites found no uses of the technology.”

What it means for Copernicus? It means that Copernicus will not be as easy to access as it used to be. A week ago, anyone having Windows system and IE could access the system without any problems. Now, one need to add http://www.3dwiki.net to the list of trusted sites and lower the security level so ActiveX components can be run in his or her browser.
