I'm having problems doing the load / re-save thing... I've downloaded Parabellum's "tutorial01.miz", popped it into the mission folder, loaded it in mission editor, gone to "save as", but clicking on "save" does nothing. Even if I rename it or try saving it to a different location, all I get is the save button being pressed, but it doesn't actually save, and the save dialog just sits there. Most odd.
