Trying to work on a 5mb+ SQL dump, I discovered something else: PSPad did NOT crash with line wrapping turned off. The file opened fine, though not having the lines wrap meant that I had to scroll through lines that were probably thousands of characters long.
BTW: Notepad++ wouldn't even start trying to open this file; I ended up using sed (on my server) to do what I had to do. -- <http://forum.pspad.com/read.php?2,53090,56474> PSPad freeware editor http://www.pspad.com
