Using NTFS-3G is the only viable option for me because I double boot Linux and Windows and use uTorrent in both on the same data folder. However, I could not think of a way to reproduce and quantify this. More than that, I did not saw this recently. Maybe it because of new Wine workarounds in the current version of uTorrent.
