[NTG-context] Search problems in large source code (unwanted paragraph breaks)

Hello ConTeXist. During the compilation of a large source code that contains many macros, I get paragraph break in output. For a long time, I am looking for a place where this problem occurs. I've tested manual checks and turned on many different trackers (for example use \enabletrackers[context.trace] from wiki) to see where the problem is, but I can not figure out the solution. Does anyone know how this problem can be addressed? In connection with this, I want to ask if there is something like \removeunwantedbreaks ??? Thanx Jaroslav Hajtmar
