Hi, I am just trying to quickly report this without joining mailing list, hopefully it works. I am getting strange error reports with hebrew words and ConTeXt IV. Error is following: "error: /usr/share/texmf/tex/context/base/font-otn.lua:1809: attempt to index local 'chainlookup' (a nil value)". My suspicion is that this could be some regression bug introduced to ConTeXt IV. This is because I could not think anything I have done wrong and my testing file is very simple. I also have earlier standalone ConTeXt IV that does not give this error. Exact details can be found from tex/stackexhange where I initially started to ask around. I post this thing here only to make sure that this catches the attention of the right people. Question in tex/stackexchange: http://tex.stackexchange.com/questions/41052/hebrew-words-causes-strange-err... Thank you, Simo Ojala
