(Preallocation method was set to simple (slow))
If I download only parts of a torrent, that is, deselect some of it's files and later reselect them, the remaining space on the partition does not change, though the files are created and have their appropriate size.
I.e. open a torrent for files a and b, select only file a, space is reserved for that file just as it should. Then select file b, it's created and also has the size it should, but here the amount of remaining free space does not change.
Any ideas what this could be due to?

Currently files you select when the torrent is already running, are not preallocated (not fully at least).

We are gonna add this once the port to KDE 4 is finished.
