On my Windows 2000 machine at home, until a week ago I could navigate to a web page by entering "www", etc. Suddenly I had to start preceding "www" with "http://" in order to go to the desired page. Not that it was a big deal to type those few extra characters, but it was certainly strange behavior. After reading your posts today I uninstalled KB 908531. Now I no longer have to enter "http://". Thanks everyone. On my XP machine at work, I have noticed in the last few days that it takes "forever" using the "Save" or "Save Attachments" options in Outlook to navigate to a desired location. The computer just sits there for about a minute each time I change drive letters, folders, etc. From what Microsoft is reporting about 908531 I may just try uninstalling this patch from that machine as well to see if it resolves this problem.
