Confusion about game saving

[Raen]

I have both the full game and the demo. The full game was installed after the demo was.

I've been trying to sell a friend on how good the game is and he got the demo and we played a demo game together. But this morning I'm surprised to discover that our demo game was saved in my main (full) dominions directory. Are you consulting the registry to determine where to save games?

Does this mean there will be a problem with multiple installations of Dom? Suppose I want to host a game and don't want submitted pretenders to overwrite mine?

Or did I accidentally start the full Version when I played him and not the demo?

Confused....
