I set DuckDuckGo as my homepage. When I later wanted to use a different search provider, DuckDuckGo would not allow it. Every normal avenue I attempted was prevented, and DuckDuckGo remained stubbornly my search provider. I finally did a system restore to get rid of this. I was hoping to have three different search providers, to use for different needs. But now I'm afraid of your product. Something very wrong happened. I am not the only guy who has had a problem. Bad duck.
