Pages Bold
Pages is suddenly making an entire previously typed paragraph boldface even though no command to do so has been given. This has happened several times. I have to go back and reformat the paragraph to remove the boldface. The boldface seems to relate to a button (appears in the upper righthand corner) that says "Update." Does this Update button create the boldface? What is the function of the button?
