Regarding alobpreis' suggestions:

• Disabling extensions and the problem still occurs.
• Going to the blog using "in private window" mode and the problem doesn't occur.
• I know where to find developer options in the menu but don't know anything about what I am seeing.

It would seem that somehow the Opera browser in this machine thinks it's in India and there should be a setting or a work around.

Here is a little more information.
This problem only happens with Opera and only one computer, not my second computer. It does not happen with Internet Explorer and not just with my blog. I can type, paste or click on a blog link and the blog comes up but the extension in the address window is changed from dot com to dot in.

When I type my blog address into the opera browser window the correct blog comes up but the address extension is changed from .com to .in. I am in the USA no India.
Any ideas why this is happening?

Abrir la barra de tareas y propiedades del menú Inicio , haga clic en el botón Inicio , en Panel de control, en Apariencia y personalización y, a continuación, hacer clic en la barra de tareas y menú Inicio .
Desactive la casilla de verificación Bloquear la barra de tareas .
Seleccione la opción Ocultar automáticamente la casilla de verificación barra de tareas . La barra de tareas está oculta a la vista .

Yes, I think something bad snuck into my machine.
The reason I wanted to change the search engine is because it was only doing it with Opera and only Google. I did a system restore which seemed to fix the problem then saw Donq's message and ran ADWCleaner which was good advice.
Now I'll see what happens.

Google has started popping out ads from the side when I go to certain web pages which covers about a quarter of the webpage. I find no cure by searching Googles ad preferences page.
Is there a way to switch to a different search engine in Opera ??

It is a problem within Opera and it is being worked on.

Yes, I think he means Google Search. How do you do it?

Visiting your "similar thread" I failed to see my specific situation described.
Also:
Looking in the mirror I suspect you are mistaken about me.
Is it possible that you are joshing me?

Just to be perfectly clear about my problem I will explain it in more detail:
I like to read my favorite daily comics every day so I keep their links in a folder. Clicking Ctrl along with the left mouse button on the folder should open all the comic strips in separate tabs at one time. This hotkey used to work with opera and still works with my other browsers but now no longer works with my Opera version 34.2036.25.
My question - is there a fix for this?
Thanks

I posted an incorrect description of my problem.
I should have said that when I click Ctrl+left mouse button.
