I have a webpage showing as a window on Opera's page tab that cannot be opened - i.e. it just appears on the page tab, but clicking the page tab to make it active shows nothing.
http;//search.kelkoo.co.uk/shopbot/NR-popup.jsp?from=quicksearch click here
click here is some kind of search engine, it looks fairly innocuous, but I am puzzled how this page got loaded, and what purpose it serves. I can close the window and reopen it from the history or closed windows menu.
