I can't reproduce this every time, but I've taken screenshot to prove it's not just madness....
Note how between the bottom of the question and the bottom bar, there are no page navigation/size links. Also the "PEAK" bit overflows on the right.
Here's what it should look like:
Chrome 5.0.375.99 (beta channel), Windows 7.
EDIT: I've just seen it again in one window after opening 4 in a row... and the bottom question shown is the same for both the broken window and the working one, so it is getting all the questions...
I didn't mention before, this is the Questions tab, set to "Newest" sort order and 50 questions per page.
EDIT: I've also just seen the same thing on IE8. I don't have Firefox on this box to try to reproduce it there, but I can do so when I get home.
