Hi, I do not have the very latest beta of Context. I am using This is LuaTeX, Version snapshot-0.35.0 (post_contextgarden.tex ConTeXt ver: 2009.03.18 21:58 With this version, I found something that does not work in Tikz when compiled using MKIV, but works when compiled using MKII. Is this a bug in MKIV that will be fixed soon, or is this due to some fundamental incompatibility between MKIV and Tikz that will remain until Tikz package is modified by the Tikz development team. \usemodule[tikz] \setupcolors[state=start] \setupcolor[xwi] \starttext \starttikzpicture \node (S) [rectangle,draw,text width=2in,fill=linen] at (0,0) {The "fill=linen" option works with MKII. But does not work with MKIV. If I replace "fill=linen" with a Tikz option,such as "fill=blue!20", everything works fine with MKIV}; \stoptikzpicture \stoptext (the quotes are used just to draw attention. Not entered in the actual code)
