Here's another (small) programming bug and that bug shows up when one changes the language in RECUVA (RC). I ran RC with the dutch language selected upon start up and then changed the language to english. I wanted to undelete pictures only. So I clicked on the arrow next to the drop box (see inside the red circle in the attachment) but only dutch words showed up in the list. Then I choose ""Afbeeldingen"" (dutch for ""pictures"") and then RC correctly shows the english word ""pictures"".
So, it's clear that RC forgets to refresh the content of that particular dropbox list when the user changes the language. It's nothing fatal but a tiny thing the RC developers overlooked.
