[NTG-context] Latest beta, simpleslides, and font loading

In the latest beta if I use the simplefonts module, the font database is regenerated at each run! For example, this file For example with this file: \usemodule [simplefonts][size=10pt] \setmainfont[Cambria] \setmathfont[Cambria] \starttext \input knuth \stoptext the font database is regenerated at each run. If I replace the simplefonts setup with \setupbodyfont[cambria,10pt] the database is not regenerated. Any idea what is going wrong? (In my actual document, I am using system fonts, I would like to use simpleslides module rather than write my own typescript). Aditya
