changing default kmail browser

greetings, one and all . . . there is a setting someplace that i cannot find, and it is making me crazy. well, crazier. everywhere i can, i have set firefox as my default browser. but kmail won't listen. no matter what i do, when i click on a link in an email message, here comes konqueror, which is a great file manager and a terrible web browser. i very much hope that this behavior is not hardcoded. have set firefox as the default in the kde system settings through kcontrol (and the other places, such as konqueror configuration, where the same choice appears) and it seems to have taken -- everyplace except kmail, which is where it chiefly matters. anyone know where i can change this? thanks. -- dep The shortest distance between you and great fingerstyle guitar playing?
