I just looked at my loaded game.
The game screen is 3/4ths the size of my puter screen.
The communicator is the left ornate on the bottom left of the frame. It has a botton just under the magnifying lens. I think it's red in color. Click that you will get the options.
I can't remember if I used both CDs during the full install - Here's the homepage - www.tivola.com
and also firstname.lastname@example.org or email@example.com.
BTW, there's a wt in CD1 that can be read using Acrobat Reader.
Hope you get it going!
