Scenario files created on Win32/Win64 contain [absolute] Win/MSDOS paths, which canot be hacked by the UNIX version, and vice versa.
The fact that those paths are always stored as absolute paths also makes the scenario files non-portable across various systems, even though they might run the same OS: when your abs path is different, the scenarios will croak.
A possible solution out of this predicament is to store relative paths in scenario files, and always have those UNIX-formatted. Question is: relative to WHAT? pavuk binary? Some imaginary/common-heuristically-detected base directory?
