Fair enough. Consider the following MWE: \starttext $\hbox{gt}_{gt} {gt}_{gt}$ \stoptext Attached are two versions, one typeset with “texexec --xtx test.tex”, the other with “context test.tex” (should be obvious from the file name). In the LuaTeX version the subscript drop is considerably larger than in the XeTeX version. > > - afaiks your \math font is not set up as math > > Hans > > > ----------------------------------------------------------------- > Hans Hagen | PRAGMA ADE > Ridderstraat 27 | 8061 GH Hasselt | The Netherlands > tel: 038 477 53 69 | www.pragma-ade.nl | www.pragma-pod.nl > -----------------------------------------------------------------
