Re: [NTG-context] Vertical space around displayed formulas

18 Jan 2017

      Hi Nicola,

Indeed there is a recent bug, reported by Mikael Sundqvist a few days ago, and Hans is aware of this. 
Hans said in the next release of ConTeXt beta the issue will be fixed.

Best regards: OK

Hello,
has something been changed in the last few months in the vertical
spacing of displayed formulas, frames or other environments?
I am re-typesetting some presentations using the latest beta and the
content of slides (especially those containing formulas) now tends to
flow to the next page, while before it used to fit in one page.
I paste below an example, if that helps. I am using a system font,
so you may not be able to reproduce my problem without it.
Is there something I should change in my documents?
Nicola
