You can practically get Option 8 using Option 2 alone. Right right click like mad on your destination when using Num2, and refresh the option as needed. You can cross the entire world in one turn, just by using Num2, and never have to deselect your chosen army/navy.
mine hangs also when I click things, but not that long, just about 2 seconds. overall it's fine, no lags in battles, no crashes, no problem. only some crashes when I used unpatched trainer with a patched game.
therefore... I think this is a very good game, very good game play in campaign mode with trainers.
