in the future, limewire will communicate with other limewires as often as possible without actually exchanging the real filename. instead, they will use 'hashes' of the file. this way, someone could start downloading file XYZ.doc, stop downloading, have the other end rename the file (but not change it at all!) to ZYX.doc, and the first person will still be able to resume the download, keeping the original name they wanted.

there are also many improvements (again thanks to trap_jaw) that will fix most (if not all) of the 'could not move to library' bugs. limewire will now attempt to replace bad characters with a '_' and cap the length of the filename, instead of dying whenever it encounters a name that is bad. also, it will stick with the name you chose when you clicked 'download' instead of possibly changing it midway through.

i'm not sure where you're seeing transfer interrupted. that's only on the upload window, not the download window. and that generally just means the person uploading from you decided they didn't want the file anymore.
