"View source" doesn't work
Have you emptied your IE cache? That often works.
Make sure notepad.exe is in ..\windows and that it is not a
third party version. Also, make sure that there is no
shortcut to notepad.exe on your desktop.
Also, search your registry for the DWORD noviewsource. If
that exists, delete it or set it to 0.
Have a look at these site for hints:
