I just now installed DSS 5.11. Using Windows 7. In previous versions model notes showed completely in one "Message from Vensim" window upon opening a model. In 5.11, the model notes show one line at a time in multiple "Message from Vensim" windows, a new one of which opens each time you click "OK" on the previous message window. This makes it very difficult to comprehend the model notes. I first noticed this problem in a meeting yesterday when a colleague opened my model with model notes, but didn't know why. Today, after installing 5.11, myself, the same thing is happening to me, so the problem has been replicated on two machines, both 5.11 on Win 7.
