Version: 4.0.99 (using Devel) Installed from: Compiled sources If you try to open a file ie, "kwrite this_file_does_not_exist.txt" and enter text it will be invisible, its being entered so if you save it and cat it to console it will appear. Likewise if you open kwrite from the menu and type text in it and save it, upon re-opening it will be invisible.
