This new version does have the +1 position incremented, as you said, however, when I download files using the {pos:2} field, I now get the following unusual output for the position field:

The B-52's - Cosmic Thing (1989, Rock) - 01 - Cosmic Thing.mp3
The B-52's - Cosmic Thing (1989, Rock) - 11 - Dry County.mp3
The B-52's - Cosmic Thing (1989, Rock) - 21 - Deadbeat Club.mp3
The B-52's - Cosmic Thing (1989, Rock) - 31 - Love Shack.mp3

... despite the fact that the "Position" column in the main window clearly shows those tracks as being ordinary 1, 2, 3, 4 in position.

Is there a "position = position + 1" statement somewhere in the code that's being misinterpreted as a string concatenation instead of a numeric addition?
