Emmanuel,

Just as OKH reported, the slow update of the 3D-image happened more than once. Unfortunately, I cannot reproduce it. It was very rare, and if I were you, I wouldn't worry too much about it.

There is another anomaly. Sometimes when a pop-up window appears, it appears blank. That is, the window appears, but not its contents. With Escape I can "close" the window again, and the next time the window appears normally. This has happened in earlier versions as well. (With pop-up window I mean the window for Modify walls or Modify furniture or something similar.)
