Manual sorting in listview does not work correctly anymore if you try to move a file down with ALT-Down.
As soon as you reach the last file to be seen in the window moving further down does not scroll in the list.
The file is put at the final end of all files.
Scrolling up is still functial.
I don't know exactly how long this bug is present and with which version it was invented. I think it has to be version 2.80 because I work quite regularly with MP3Tag and I have not noticed this bug before.
I crosschecked this behaviour in an old installation with version 2.75a and there the bug did not occur.
Maybe this wrong behaviour came with fixing the scrolling bug in websources in version 2.80.
