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.

Yes, this is the "expected behavior"! You have to protect using the pointer to the PostStep's physical volume. It is NULL for steps ending at the edge of the 'World Volume'. (Let's not discuss why this trap is in G4 - I have argued and tried to convince my collaborators for years that we should spare our users but to no avail - What it would take is an automatic "OutsideWorld" volume that is of the same shape and just a bit larger than the one instantiated by the user.)
