--- Comment #5 from Fabian Maurer dark.shadow4@web.de --- If I click "Scanning Options" a new windows opens, seems to work. Let's make this issue about the "Cannot open catalog file /path/to/file writing" error.
From time to time I get a "Window class name is not valid" error, but that's different as well.
