Hello, We have a document where a gap occurs in a columnset under certain conditions. It seems to be a confluence of: - 2 sections, each with 2-column columnsets - \page[empty] between them - the 2nd section has a tighter interline space The problem is that on the first page of the second section, a two-line gap appears where gridlines 50 and 51 are. It may be a coincidence, but 50 is also the number of lines per page in the first section. We've found that "coincidence" to be true even with different page and font sizes. Can anyone tell us a way to get rid of the gap? We've tried things like \setupcolumnsetlines[columnsetbibliography][1][1][-1] \setupcolumnsetlines[columnsetbibliography][1][2][-1] with various values for the last parameter, but nothing helps. Below is a small, self-contained sample. Thanks for any help you can give.
