"View Source" quit working in IE 6.xx

I'm running Windows 2000 Pro with IE 6.xx. Installed all updates through microsoft. All of a sudden, I am unable to view the source of any web pages. Notepad no longer pops up with the HTML code in it. What changed? Is there a registry edit I can change or is there something in the IE Security settings that got changed? I'm running the system as Administrator so permissions don't appear to be an issue.
