some of the configuration pages for the Memberlist addon are going below the text that is at the bottom of the page. If you click on "Display" then go to "Stats List", the page looks fine. If you click on "Member List" and then "Stats List" the page will be over the text at the bottom of the page.

I've seen this too, on other config pages. I think it's a browser rendering issue.

Could be. I am using firefox.

I have seen this as well
Weird how it doesn't happen in 1.7.3
