See title. This is on debian testing x64, both the packaged version and compiled from source. http://i.imgur.com/sZBadm4.png I compiled the source as from http://goodies.xfce.org/projects/applications/xfce4-screenshooter, ran it, and that is what you see (I captured it with the packaged version as that was quicker to start) It's not a major issue, but if you are alt-tabbing through your windows it may be slightly confusing to see that it's still uploading. The window does close when you dismiss the window with the links.
