I know it must be hard to check on previous comments, but people already said a couple of times that, if you go to the preferences menu, you will find an option called "Textbox Transparency" and a slider. If you move that slider, it wil show the text box, you can set it to however you want, full text box, or just a little so you can also see the background.
This is already fixed for the silver release, and from now on it will start with the full text box showing when you start a new game, and then you can set the slider to change the transparency of the text box.
