So in some sense it does what it is told to do;-) > Omitting the "cmd" could be a solution. Does it have any use to add the > latexEnvCmdPrefix to a viewer command ? This looks rather wrong to me. This should only be added when running a TeX related converter, e.g. LaTeX, BibTeX etc. There are more dangerous code parts, e.g. subst(command, "cmd /d /c ", ""); looks quite fragile. > Other solutions using QProcess::start did not work as I never seem to > get a finished() signal to be able to delete the process.

Yes, there are many ways to do subtle errors when creating child processes (a long time ago I wrote cross-platform wrapper for that which took quite long to get it right), so we should not change this right now. However, if there is an easy way to use latexEnvCmdPrefix only for converters it would probably be good to do that. Georg
