I have Yahoo set as my homepage--don't ask, I just do. Recently,Yahoo has started loading the page in such a way that the web search box is the last thing that comes up, and when it does the cursor moves there automatically. So if you've started typing a search term into the Safari url/search box, you find that half way through typing the stupid thing has jumped to the Yahoo search box and you've got to move back to Safari or type over again and just accept that your default search engine has become Yahoo, whether you want it or not. I hate it so much that I may change homepage.
