I'm using portable version 22.214.171.1240 (as we can't install software) for the first time. I'm trying to copy a DVD and I've selected Copy Data Disc. It reads the disc to copy no problems, gets to 49%, pops out the disc and asks for a blank one. I put in a blank one but the screen never changes. The popup window asking for a blank disc, which says it will register when a blank disc has been entered, never changes or goes away. My only options are Eject (which makes no difference) or Cancel, which stops everything and gets me no where. What am I doing wrong?
