Hopefully there is a configuration cure to avoid a bug report. Any file that is opened in kate or kwrite resulting in the infamous warning dialog that the file is binary and editing will result in a corrupt file, renders both text editors into a non-editing mode. For example, create a diff file using "diff -urNa" where there are file additions or removals in the target directory. Open the diff file in kate or kwrite. The infamous warning dialog appears and editing thereafter is impossible. Also disabled is searching and seatch-and-replace. Bug or configuration problem? Darrell
