I have found what could be a bug: for the last two videos I have
uploaded, the new uploader just goes on and on and on 'uploading', but
my PC says the Internet connection is no longer being used. When I
check My Videos in another browser tab, the video is there, but with
no data entered during the upload (title, description, etc). So I just
cancel the upload and enter the missing data separately. However, if
this is a bug, it would of course be nice if it could be fixed before
the new uploader goes final.
