Something strange happened here with the interaction in a pdf produced.
There are chapters reacting when clicked in the table of contents but some are not. Moreover, this behaviour changes with the version of context used.

I tried 3 versions of the beta:
ConTeXt  ver: 2013.10.15 13:52 MKIV beta
ConTeXt  ver: 2013.11.10 12:23 MKIV beta
One specific chapter does not jump to the starting page when clicked.

ConTeXt  ver: 2013.12.04 11:34 MKIV beta
Nothing changed in the source but now another chapter link also becomes inactive!

There is no ready explanation I can think of. Because the document in question is about 500 pages I do not yet have a minimal example at hand. And as I suspect the problem can have its origin in the complexity and/or size of the document, I fear the construction of a minimal example will be difficult. Therefore I am first asking if this problem is known already. Afterwards I will try to find a small example, of course.
