First to say - on linux, I dont have any problems. I use QProcess to start everything and it works.

First trap - Windows. I can start anything, but for tools using the shell. QProcess::start does neither start cmd.exe (with complete path) nor any tool from cygwin (mc.exe, vi.exe, bash.bat). The only way to get a command line is to use QProgress::startDetached. But then I don't have any chance to set the environment of the shell...

Second Trap - Mac. When my app is already started within the bash, and it starts another bash command, the new shell is opend within the window of the starting shell When the app is started from the dock, starting a command line does nothing at all. Neither QProcess::start nor QProcess::startDetached opens any window at all.

Any suggesgion is welcome
