Yes, I'm having the same problem with my Acer computer. Any time a put a cd or dvd in the drive I can very rarely access it from windows explorer. Only after several days, for whatever reason, will autoplay, or the explorer window spontaneously open with the contents of the cd or dvd. Then I feel compelled to keep the window open or lose access to the contents of the drive.
I have suspected this green bar before. Does anyone have any solutions?
