Seem so, although in your case it's working as desired. You must have unchecked the "throw with discs at me when you're done" preference. Nevertheless, the Plextools need to reset the drive after burning. It seems as if the disc hasn't been finished yet, but in fact it has. So, the disc is ejected, and because you don't like that, it is loaded again. They should build in an "I'm sorry" sound for that .
