I haven't reported this before now, because I thought it was so obvious that there was no way it wasn't going to be fixed in the next release.  With each release I kept thinking that, but maybe it's not happening on other machines then mine. 

What's happening is that the background text from whatever screen is up is showing through the window of the various dialog boxes, so that the text from the back ground screen and the dialog overlap.  I will try to go back in game, and post a screen shot in another post.
