@Innsewerants: For some months I wondered, why ISA Mapsat 4.0 Dev. did not run on my Linux box until I found a hint in a forum entry, that the 'hilo.dat' file should be renamed to 'Hilo.dat' (capital 'H'). Since I did so, Mapsat runs perfect on my Ubuntu 13.10, x86_64 machine. Today I looked into the old source of Mapsat and checked, if I can find the reason for this behaviour. I found there, that 'Hilo.dat' is written with capital 'H'. It seems that ISA_MapGen.exe (I use it, as found on another forum entry, on Linux with mono) uses hilo.dat without cap 'H'. Maybe, if it's still the same reason why hilo.dat is not accepted by MapSat 4.0 in Linux (game crashes on switch to launch pad) you might take care of that in future versions. Thanks for the really nice Plugin! :-) Handir
