Hi,
I think I found a bug. I use the German version of V.2.19B.
If I click on "Ansicht" -> "Sortieren nach" -> "Dateiname" "Dateiname" is only available if I have selected at least one file. Otherwise it is grey. And when I have selected some files I get the same popup window as Ansicht Tags... (ALT+T).
Regards,
Julchen
