In a LyX file, there is some ERT which I have centered using LyX's paragraph layout controls. At one point, I decided to put "%" at the beginning of the ERT, so that it would not be processed and save time in drafts. Well, it seems that the centered paragraph layout of this "%"ed bit of ERT bleeds through to the rest of the document, causing centering of everything from headlines to text. -- -lsm
