Hi everybody, I've got problems with typesetting binomial coefficients and arrows in math mode on ConTeXt ver: 2009.03.27 08:00 MKIV on Win Vista. Binomial coefficients: The brackets stay small (usual size like in plain text), here's my code: starttext startformula {achoose b} stopformula stoptext In fact, it seems atopwithdelims() isn't working because the problem can be fixed by adding delimiterfactor=1001 defbinom#1#2{left(#1 atop #2right)} starttext startformula binom{a}{b} stopformula stoptext The second problem is much more bothering to me because I can't typeset limits in right way - the arrow under the "lim" is omitted (both ways fail): starttext startformula lim_{trightarrow 0}f(x) stopformula startformula lim_{tto 0}f(x) stopformula stoptext The commands leftarrow, longrightarrow, longleftarrow etc. aren't working too. On the other hand, uparrow works just fine. Please, tell me what I'm supposed to do to fix it up. Or is it a bug in this version? Thanks a lot, Tomas
