Upon installing there are twee wizards.
The first when where you set resolution audio etc, which is followed with the sweet little lady.
Recently when installing I select resolution, and the screen is regenerating but I see the second wizard instead of finishing the first.
After a while the first wizard kicks in and I can continue.
This happened to me with the DVD-Beta1 intallation and the net-installation.
I am using virtualbox, which didn't have this problem before.
