- 7. Right-click disabled by Web Page
Some web pages implement a restriction to stop visitors from right-clicking on the web page; usually to stop the saving of media. The source may still be viewed by using the menu: View > Source.
- 8. Missing Notepad.exe
The View Source function uses Notepad to display the HTML, if "notepad.exe" is missing from the Windows directory then it will not work. To resolve, ensure a copy of Notepad.exe is in the Windows directory.
