Thks. I was incorrectly assuming that the dimension properties, especially width, should be set in \definelayer. I'm not clear on the purpose of a separate \definelayer command, unless it's to allow the abstraction of layer offsets from topspace and backspace value, the way I have in this example.
It works now, though, and I'll accept that as an answer given my unwillingness to review that code for \definelayer ;-) -- david ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
