Opera re-downloading files if they're being used
I use Opera to download video files. I often watch them while they're being downloaded (opening *.opdownload in VLC). However, since an update (it's been a while), this becomes tricky. If the download finishes while the file is open in VLC, Opera will delete the downloaded data and force the download to start from the beginning which is very annoyoing. Is there a way to prevent it?
