Yeah, I think that has been the case for a few years. When I ran into the same issue I made my own version implemented in Java. You download my version (rm.slice) here: http://www.rothmichaels.us/roth-moves
At some point I will get around to fixing those things and adding some new features, but right now I am busy working more than full time on many projects—it should work fine as is. I'll post to that thread I linked above when I make some changes.
