Hi guys, i've already searched the mailing list for this but i still am having a problem while trying to create a matrix. my code looks like this: \startformula S=\left(*\matrix**{* \sigma_x *&* \tau_{xy} *&* \tau_{xz} *\cr* \tau_{yx} *&* \sigma_y *&* \tau_{yz} *\cr* \tau_{zx} *&* \tau_{zy} *&* \sigma_z *\cr* *}*\right)_{xyz} \stopformula But since a few days, there are only empty braces after compilation. The funny thing is, i worked already. but i've updated context at least once since (only 5 days ago, betas included) and since then after compiling there are only empty braces. When i enter \startformula S=\left( 1234 \right)_{xyz} \stopformula the 1234 shows fine between the braces. so it seems to have to do with \matrix command in some way... i don't know any alternative way to create a matrix. any help would be appreciated. Greetings, Sebastian
