--- Comment #1 from Marcin Gryszkalis <m...@fork.pl> --- I guess configuration screen should be fixed anyway, though in current git version there's following code: krviewer.cpp: 313 if (editor != "internal editor" && !editor.isEmpty()) { and both soultions (given string or leaving the field empty) worked for me. Can you try latest git? -- You are receiving this mail because: You are watching all bug changes.
