I have set my questions per page to 50, going to the last page (http://stackoverflow.com/questions?page=88934&sort=newest). The first time it showed questions with id 4, 6, etc.
Then I tried to forward few pages, I got this:
Page Not Found We couldn't find the page you requested. We did, however, find this program. Try searching for similar questions Browse recent questions Browse popular tags If you feel something is missing that should be here, contact us.
Now when I try to go to any page in the end, or approaching the end, I get the same message as above.
