In 8.1 I attempted to make zone favorites that included codes for floor finish, wall finish, ceiling, etc.. What I found is that the Favorites palette has a quirk that renders zones useless for my purposes. If I defined a dozen zone favorites, then saved them to a PRF, they worked fine. However, if I defined an additional dozen zone favorites and resaved the file, the original dozen would no longer have the finish codes. This behavior continued no matter how many zones I defined -- at the end, the only zones that worked were the last group that I defined.
So now I'm working with AC9, blissfully assuming that this problem was fixed. But noooooooo! An hour into the process, it occurred to me that I ought to check some of the zones I defined at the beginning -- no finish codes!
