Dan, I'm working on a string quartet and whenever I play the score from a given point, I usually stop the score by pressing escape in midperformance in order that successive playbacks will start from the original point, wherever that was. When I do this, I get the erroneous message that the properties window is closed and needs to be opened. Go to the window menu and make sure that the properties window is checked. I have gone to the window and it is indeed checked. Not only that, I can visually see that it is available as ever. Using the space bar to stop playback is not desirable in this case as the next playback will resume from the stop point. Just thought you'd like to know.
