When choosing audio froom the main menu it is very slow in loading the audio burner and even sometimes indicates "not responding". Once loaded the disk burns just fine and with the usual speed but when burning multiple disks, it will finish a disk and eject it but take some minutes before asking for the next disk and indicating completed burning of the disk on the dialog screen. Again, if you try to click anyhthing it indicatges "not responding". Same is true after burning the last disk. It is ejected promptly but it takes a very long time for the close screen to come on to allow you to return to the audio burning screen. This is a dramatic difference from the mode of operation when I last used it a few months ago. Using version 220.127.116.1123 64 bit on windows 10.
