Version: 3.2.4 (using 4.2.4 (KDE 4.2.4), Kubuntu packages) Compiler: cc OS: Linux (i686) release 2.6.28-11-generic When you continue to type in a long line (400 characters definitely does it), typing becomes extremely laggy. Characters often begin to take up to a half second to appear. Going to a new line usually fixes the problem. This issue is also very prevalent in KMail, which may or may not use the same editor component.
