The pausing issue on Linux is due to a small oversight inside the plugin (already present in the v3 code from the OP). It checks if Hilo.dat is present, if not generates it (that's what's causing the pause), and then writes this data to hilo.dat which of course means it won't find it again on the next run. (Gotta love Windows-centric development, dontcha? ) Simple workaroud: Open a terminal, cd to Innsewerants Space Agency/Plugins/PluginData/ISA_MapSat/ inside the KSP GameData directory and do ln hilo.dat Hilo.dat. This will create a hardlink between the two names ans MapSat is none the wiser. (I didn't test if a symlink works, it should though).
