Once Fab has finished reading the contents of the source drive, the "Open DVD source F:\ " window will continue to pop up every few seconds, even after selecting the "Next" option to advance to the second screen or second step of the copying process.
Every time the "Open DVD source F:\ " window appears, the program will kick the user back to the FIRST screen or step in the copying process. This makes it tough to edit the volume name, as you've only got a few seconds to type it before the program kicks you out of the screen.
This has been going on since the release of version 8.
Funny thing, it's not actually targeting the source drive (which is G: on my system); according to the pop-up, the drive it's actually reading is the destination drive (F) on my computer, contrary to the "Open DVD source F:\ " message.
Once the user manages to click the "Start" button (you have to get to it fast!), the program stops popping up the "Open DVD source F:\ " window.
This is on Windows XP SP3 and version 126.96.36.199 of the program; but, like I said, this has been happening ever since the first release of version 8.
Perhaps no one wants to support the program on XP, but I'm hoping this can be ironed out.
