I start to download something, be it from a nzb, from a search of from browsing a group.
Halfway through the download I change my mind and delete the download from the "Downloading files" tab.
All the downloaded files are deleted, but left are, usually, a bunch of *.nb2-files that looks like half-downloaded files or something. The files are locked by newsbinpro64.exe and can not be deleted, moved, copied or even opened.
The only way to get rid of the files is to restart Newsbin. If I close Newsbin, the files are still there, but they can now be deleted...
Please...fix
