Hi all, I would like to get some advice concerning a problem, or rather a nuisance, with internal references. I am making a longish document with several chapters, all of which are separate .tex-files to be input into the main file, which contains all setups and the skeleton of the document. There are a number of cross references between elements that sit in different files. With some simple test files I checked that this worked and that I use the proper commands. However, with the real files it does not work, that is, not immediately. Even after 4 or 5 runs I still get ?? instead of page numbers, and then suddenly things are OK. I have no idea what happened between failure and success and I have no idea what I have to do to get the proper result immediately. It is a nuisance because I cannot be sure the thing worked till I have checked the entire output after each run, which is rather time consuming. I’m using the latest version of TeXShop with the minimals of july 20, but older versions show the same symptoms. Thanks for any advice. Robert Blackstone
