Version: CVS (using KDE Devel) Installed from: Compiled sources Go into configure/editor dialog for KATE. Pick highlighting. Pick highlighting modes, tab. If you change anything the check for Use Default Styles will go off. Rechecking this does not restore the default sytle. It looks like it is on, but exit the dialog and reenter and it will be off again. If you uncheck it there is no way to get it back on except to delete the config files manually.
Kate behaviour. Reassigning.
