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.

Thanks for being so careful and checking my replies for consistency. I was wrong when I said that groundfrontpainted in dielectric_dielectric and ground in dielectric_metal are equivalent. This is no longer the case since when the ground dielectric_metal surfaces also take the UNIFIED reflection parameters into account.
