Just a little concerned about picture editor support. All modern graphics cards - even Intel integrated graphics! - ought to support it, but I've heard it doesn't work for everyone.
If it doesn't work you should update your graphics card drivers
and try gain. It may only be supported by the latest drivers.
If it doesn't work, please also post your OS and graphics card!
(When it doesn't work, it'll prompt a message box and launch an external editor like it used to. If you see any built-in editor at all, that means "working".)
