The mom macros don't exhibit the behaviour. I wouldn't have thought it possible. The question isn't why should it, but how could it? The only thing I can think of is that the .bp is triggering a macro that changes the .vs. That could result in different vertical placements, but not, I think, "noticeable." -- Peter Schaffter https://www.schaffter.ca
