When the browser window width is within one pixel of forcing a word to be placed on the next line, sometimes the last line in a sentence gets repeated. I can duplicate this at will, with any post. Just very slowly change the browser width and then scroll up and down through a thread. Odds are that one of the sentences will have a repeated word at the end and beginning of a line. Change the browser width by even one or two pixels and the word wrap problem goes away. I am using the latest and fully patched msie and windows 7 pro 64 bit. It looks like there is a boundary issue where the word wrap decision uses greater than and less than, instead of greater than equal and less than, so when the number of characters fits EXACTLY on a line, it duplicates the last word as the first word on the next line.
