I've updated to the latest version. These particular bugs are still present and have been for months.
Another bug I hadn't noticed previously involves the Preview feature: The stop button does not work. Because of this bug, users cannot "stop" Preview play, which effectively cripples ripping. Users can pause video with the Pause button, and this seems to allow for ripping. But the Stop button should work, regardless.
The bug causing the software to jump back to the "Source:" screen when ripping discs seemed worse in 188.8.131.52 than in 184.108.40.206; that is, it happened with more discs and within a shorter time frame than before. I can't say yet how frequently it occurs in 220.127.116.11.
