I thought that typesetting should start after \startext and that anything before it should be ignored. That is indeed the case with the following input:

ABC \starttext CONTENT \stoptext

But add a \setupbodyfont and suddenly the ABC appears:

\setupbodyfont[lmodern] ABC \starttext CONTENT \stoptext

Is this correct behaviour? It is a nuisance because this phenomenon causes a spurious blank page appears in my book. It might be a recently introduced because I did not experience this in the past.

There appears nothing in the first case because context delays font loading until \starttext but when you add \setupbodyfont a font is loaded and text is no visible. When you something in your document before \starttext which creates a blank page something is wrong with a macro and you put something there which shouldn’t be there. Wolfgang
