I used PhotoRec today to recover accidentally deleted tif-files, and it worked fine, recovering almost half of the stuff I wanted. After a while I checked again and saw this screen. Wondering why the show wasnt going on I tried to stop the thing, but it wouldn't react.

Closing the terminal did the job, but when I reopened PhotoRec and asked to resume the recovery, the same screen came on, as before not ractng to the "stop" command.
Any ideas? Thanks in advance.
