Hi there, after upgrading TL2011 today and having installed a new version of simplefonts, I cannot get this sample working: \usemodule[simplefonts] \setmainfont[TeX Gyre Pagella] \starttext \TeX \stoptext The error I get reads: ! Undefined control sequence. system > tex > error on line 2 in file a.tex: Undefined control sequence ... 1 \usemodule[simplefonts] 2 >> \setmainfont[TeX Gyre Pagella] 3 \starttext 4 \TeX 5 \stoptext 6 7 \setuppapersize[A4] 8 \setuppagenumbering[alternative=singlesided,location=middle] 9 \starttext 10 \showlayout 11 \dorecurse{4}{\input dawkins \par \input knuth \par} 12 \stoptext <recently read> \setmainfont l.2 \setmainfont [TeX Gyre Pagella] I don't know whether this happens because I'm not using the latest beta, but many TL2011 users will face the same situation. I had to restore the package to its previous version? Would you be so kind to test it, Wolfgang? Many thanks for your help, Pablo -- http://www.ousia.tk
