At the top of the home page for each of the boards, there's a bar indicating how many pages of threads there are. Sometimes, the bar displays only 40 blocks. But at other times, it displays like 700 blocks. When it displays 700 blocks, the page becomes super-duper wide, and you have to scroll way way over to see either the extreme right or extreme left of the page. That makes it extremely difficult to connect the title of a thread to the data on replies to it.
Why does this happen? Is there some setting in the user profile to avoid this?
