There is a recurrent problem that I find lately when writing documents with the Writer application. Before starting to write a document I set its margins and justify the text but from time to time I find that, instead of respecting the margin and justification at the end of a line starting a new one, the text continues beyond the margin on the right until the edge of the page (or maybe even further, I did not try it) if I keep writing and besides an horizontal scrollbar appears at the bottom of the page. It does not happen in all the lines of a document but only a few of them randomly. I wonder what the problem may be and I would appreciate any sort of help. Thank you.
