Hi! I'm toying with a complex document environment involving multiple components, both in order to learn in general and to accomplish particular objectives. So I want a 2-column layout for all the document, which is made up of a bunch of components appended one after the other in a continuous fashion. The way I thought to acheive that is, instinctively, to use \startcolumns in my product file, before declaring the various components. However, when I do this, the use of \stopcolumns at the end doesn't work. The document does compile (with columns) when I don't use the stop command, but when I do, there is an error: ! Extra }, or forgotten \endgroup. \stopcolumns ...idecolumnsfalse \endgroup \egroup l.12 \stopcolumns What is the proper way of doing this? The thing is, I need to balance my columns, and balancing doesn't work with no \stopcolumns. Thanks! Jeff
