[NTG-context] \definerule not defined

Hi, texshow-web say: \definerule[...][...,...=...,...] [...] name [...,...=...,...] see \setuprule but it is not defined both in my and contextgarden context instalation. One from texshow or context should be corrected. I vote for the second. vit ----------------------------------- \starttext Rule: \definerule[A][spacebefore=2pt] \placerule[A] \stoptext -----------------------------------
