Hello everybody, Problem 1: I just notices that (at least for me) the $\lVert$ / $\rVert$ commands print no glyph with Lucida New Math. I search in the source files a bit, and found that in char-def.lua the lVert character is defined as U+02016 but in lucida-math.lfg it is mapped as U+02225. I was only able to reproduce this with context-current because with the beta I got some font-related internal errors when including lucida - but I guess this is another story :) but the two files are identical in those points in current and beta. According to gucharmap U+02225 is the "parallel"-symbol used to denote that eg. two lines are parallel and the U+02016 is the character usually used to denote the norm of a matrix/vector. Solution 1: I changed the entry in lucida-math.lfg from U+02225 to U +02016 and the lVert command produces the right glyph (any glyph at all :). As far as I can say, the spacing is a bit bigger than that of the absolute value $\lvert$ and $\rvert$, but that may be intentional. Just wanted to post this, if anyone has that problem too :) Problem 2: TikZ is not working in context-beta right now. a) When simply doing \usemodule[tikz] you get many errors "Undefined control sequence" for the \active command. I think this happens due some changes in the catc-ini module. I simply redefined \active with the \activecatcode macro and it compiles. b) But even then, parts of the diagram are shifted (see the examples below). I have prepared some minimal examples here: http://www.stud.mathematik.uni-stuttgart.de/~edwarddl/ I use TikZ mainly for drawing such diagramms, as it it relatively easy to use, but I use the current version for that and I simply testes the beta and it seemed not to work.
