Joining the FSX client, the FS9 client has now been added to the line up.
We'll soon have a unified installer that will allow both versions to exist alongside the original Squawkbox 4 installation, allowing users to get up and running more easily, and to switch more gracefully between SB4 and SB_PE.
Still, I think users would rather get online sooner rather than later, hence the early alpha release.
