Hi Hans, It seems that there is a bug in the latest beta (ConTeXt vesion: 2016.07.01 16:28) when using \placeformula with a framed text environment. The numbers for the formulas are placed incorrectly, on the left as well as on the right. Also, as one may see in the example below the numbering of the formulas begins at 2 instead of 1 at the first instance, and at it continues at 6 instead of 4 in the second instance.
Below is an example (sorry if it is not absolutely minimal: I ran into this bug
when updating a lecture notes which uses a left frame around \proclaim stuff).
I attach the PDF showing the problem. I wonder whether this is related to the
new features introduced recently for math frames.
The code gives correct result with ConTeXt version 2015.05.18 12:26 from
TeXLive 2015).
Best regards: OK
