That's what i was beginning to think. Thanks for the quick response.

When you press the "Control Key" and then "o" key, in windows, the "File Open" dialog opens up so you can load a file manually. It will remember the last file opened. This entry is not removed when clearing cache. I'm guessing because it may be more of an explorer setting rather than an Opera setting... I think. What I usually do when working on a computer other than mine is clear everything when I'm done. It appears to only save the last entry. As soon as I open another random file, the actual file I was working on is gone, so it's not a big deal, but I was just trying to find where the entry is stored.

After clearing ALL history for All Time including site data and preferences (everything) the Open File list is still available. (Ctrl + O) I've tried searching this in the registry, but unable to find. Any clue on where I might find this setting?

While google does own youtube, the url's are different. The ad blocker has always worked in the past. I too am having this issue. No settings have changed.
