I've been getting the same behavior from Opera 9.10 for Windows - and I used to see it in another version many releases ago. I have the web developer's mode installed, but it's usually toggled off. I noticed that all I need to do to get Opera to show that it's finished loading the page is toggle web dev mode on.
