Ah I see, thanks. That web page was most helpful.

So far it seems to me you must do this

a) First player does his turn, selects ship of second player, hits ctrl+shift+z.
Second player does his turn, selects ship of first player, hits ctrl+shift+z.
c) First player hits 'end turn' button.

The only problem seems to be that sometimes the AI takes over and does wierd stuff for the second player in between when he does his turn and the end turn button his hit (like building ships at star ports and such). Is there anyway around this or is it just part of the inherent problems to this method of hot seating?

Thank you for your help.
