Saving "Text Under Icon" settings

Moved from Gentoo/Gnome to SuSE/KDE and I'm working my way to getting things the way I like them. One problem I've run across is certain applications and/or windows not saving my "Text Under Icons" for my icons. Specifically, in KMail, if I double click a message, set "Text Under Icons", close the window, and then reopen it, it's back to just the icon. Does anyone know why this setting isn't being saved? Or better yet, a way to set this globally? Seems very trivial I know, but it's something that seems too simple and it not working is bugging me a lot. Thanks, Chris
