Could you be more clear here: which TeX engine (XeTeX, pdfTeX, LuaTeX), which output format (DVI, PS, PDF) and which viewer? For me, Evince is the default PDF viewer, so I don't see why there should be any difference. > and a random sampling of other > math symbols all worked with View > DVI. Anybody seen this before? I know that e.g. XeTeX silently drobs missing characters, as in some cases \neq is composed out of two, this could be a missing \not char. If the result depends on the viewer, there might be problems with the character composition. Maybe this could be solved by using a font-package providing a pre-composed character. Günter
