If you are having problems viewing CHM files (like the new WCF documentation CHM files), you might be seeing a blank IE screen when you click on any of the subject headings contained ni the file. If this is the case, right-click on the CHM file and select Properties from the provided menu. You can then click on the Unblock button at the bottom. This will then allow the CHM file to be viewed using IE as it should be.
