---------------------------------------------------------------------- Comment By: Alan Ezust (ezust) Date: 2006-04-12 17:44 Message: Logged In: YES user_id=935841 >From Matthieu Casanova: You can reproduce the bug with the following buffer : ----BEGIN---- aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa aaaaaa ----END---- all the aaaa are on the same line and the buffer should be in soft wrap mode. Reduce the height of the textarea to see 5 lines and paste this text. select all (ctrl+A) and past it again. Now move your caret to up and the bug should appears. Verified with latest CVS version (4.3pre4) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=100588&aid=1183831&group_id=588 |
