Thanks for checking the links fatness.
This is odd. Now, when signed in, the only thread that is too horizontal is the Microsoft Security Bulletin(s) for Sept. 11. 2012.
I came to the site without being signed in and all three "not good" links are still not good.
I followed Weirdal
advice of closing my sidebar and that fixes the problem except for the MS Security Bulletin thread, but if I scroll to the right I am able to view the posts and see the poster. So that's good.
I don't know how to disable large thumbnails and don't know how that affects this.
Sincerely, Libra
