Hi Hans, hi all, with mkiv beta (current version: 2010.06.23 12:45) and LuaTeX, Version beta-0.61.0-2010061910 (Web2C 2010) (rev 3724) my try to: C:\contextminimal>mtxrun --script fonts --reload breaks with: ...tminimal/texmf-context/tex/context/base/font-otp.lua:16: attempt to call field 'new' (a nil value) What can I do? Greetings Lutz
