Since I started using Concrete (about 4 weeks now), it happens, sometimes, that part of the piece I am writing will not change size to match the rest of it. At times, I can change it myself by switching the font from 12 pt to 24 pt and back, but at other times it will not change. How can I make all of the font equal in size?

Another thing that happened yesterday was that I could not scroll down to what was past the visual editing window--I had to use my direction arrows just to reach the words--because whenever I mouse-clicked on anything below the window line, it would all jump back up to the beginning section. How can I work with what is below the window?
