You can check the order of the installed languages and make sure that en-gb is the first choice to see if that hepls.

• Tools > Options > Content : Languages->Choose

Thanks for the reply.

Checked and that is the default language. It seems to work correctly if I choose the shopping page and then search, but if I use the right click menu "search google for something" the prices display in dollars.

So for example, if I choose the shopping page first, and then search laptops, the results display in £. If i then use the right click to search on the word laptops, the shopping results display in $, and then will display in $ for the rest of that browsing session. I have to close the browser and reopen it to get it back to £.

Pretty weird.

Do you get the other language setting back if you use Clear Recent History to clear the last hour?

Is 'en-us' or another 'en' language like 'en' installed as one of the languages under the installed?
Does it help if you only leave the en-gb choice?

Have tried all your suggestions and the problem is still present.

I tried firefox in Safemode and the problem is still there.

Thanks for your help so far.

I seem to have sorted the problem myself.

The default right click search engine was set to Google.com. I used an add on to change the default search engine to google.co.uk and everything is working well.

Thanks for the help anyway.
