Hello, I started to typeset real math in ConTeXt :-) and the following issue occurred in vertical positioning. I know about start/stopformula, nevertheless I suppose that good old $$ should work, too. \starttext A short line followed by a formula $$\bigcup_{1\le n}$$ a text follows in the same paragraph. The big cup is too close to the text. If a displayed formula has enough text above $$\bigcup_{1\le n}$$ the problem does not appear at all. The vertical space around the formula is very nice here. The only difference is whether the line above the formula goes more to the right than the beginning the formula. \stoptext Thanks, D.A. -- Jim Hacker: "Would you be surprised, for instance, if a British aircraft carrier turned up in the Central African Republic?"
