Nowadays (since update 1029fixPainter), the brush-size in force when the user exits from a painting session will be the brush-size selected when the user undertakes his next painting session. And likewise, the "currently selected color" is now remembered and restored from painting session to painting session.
If you are making an event-recording that involves use of painting, this means that you can no longer know what the brush-size and selected-color are going to be when the paint palette comes up on replay. To assure intended brush-size and color-choice in playback, you should explicitly click on the desired brush-size and color, even if on your screen they are already set correctly, during any event recording of a painting session.
