Version: 1.9.51 (using Devel) Installed from: Compiled sources Compiler: gcc 4.3 OS: Linux As a default setting, composer has the Otions->Wordwrap = On. With this setting, if I enter an URL with dashes longer than the number of characters per line, the URL is broken up after the dash ('-') as a normal word. I don't know any way to avoid this than ecah time explicitely switch Wordwrap = Off in composer when writing a new mail. The previous kmail from KDE3 did not have such a behaviour, did it?
