Hi,

and thank you for your reply and instructions!

Problem still unresolved because in my Vista Premium OS I could not find File Types tab AT ALL in the given place (My Computer/Folder Options/...)!

In my old PC with XP OS I indeed found the File Types tab fro the location you instructed.

Should the File Types tab locate also in Vista OS in the place you said, or has it dissappeared from there for some reason? Something has happened to the setting of OS since I did not have this hyperlink problem few days ago.

What should I do next?

Matti
