This has happened to me several times, I am told to visit a Google property and it turns all my Google properties (web search, gmail, etc.) into the language I just visited. For example, a Cre8asite Forum thread shows a woman who was stuck viewing French only in Google. She was desperate to switch back to the English results.
Want to get stuck using Google France? Do a search on seo and add &hl=fr to the end of the URL. Ah! How do you get back to the English results? Well, you can go back to Google.com, but sometimes that doesn't help. You can click on the link on the bottom of the Google Français homepage that reads, Google.com in English or you can once again append &hl=en the "en" for English to switch back.
