Jocelyn & Others:
Did you ever get things working normally? I'm still having this problem, and not ready to fire up AC13 yet.
I have found that this problem is more frequent when I use a file that was started in an earlier version.
But today I have two good files that were started with the AC12 template, both working fine. But if I merge the files? Then the same info-box problem occurs in the 3D window (no problem in 2D).
