Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

It's been a while since I've had that problem. It's difficult to know what caused it. I think the problem stopped when I started using the physics list from the brachytherapy example
