I have Precise 12.04 and use VLC 2.03 as my video player. My machine is mainly a media machine, so I've pretty much always got VLC open, and it's configured to have only one instance running -- doubleclick takes over the current video, but I can also right-click to enqueue to the playlist.
Anyhoo, sometimes when I have a video playing fullscreen and I hit spacebar to pause it, the context is still on nautilus so instead it launches the Sushi preview window. I think this happens when I've double clicked the file originally, launching full screen VLC, but never clicked away to change window focus. Pretty annoying when I forget to click the video after launch, which is pretty much always.
Can I disable the video preview option somehow? Or at least the launch preview; I dont' want to loose having thumbnail previews
