Tried the latest version with a couple songs. I used interactive mode only. First thing I noticed is that I have my Google preferences set to open the search results in a new window. This wouldn't work with the browser popped up. It sure didn't stop the ad pop-ups from the lyric sites though.
So I changed my preferences to get it to work.
Found my lyrics and clicked Found It. It pasted into MC fine. Now here's where I guess I don't know what to do. I clicked on the next song to work on that one but I guess there must be some kind of Save I didn't do because the previous lyrics didn't get saved. A little clarification here would be helpful.
Edit: I just "realized" what I think I did wrong. I didn't click the Start Processing Files button so I guess I was in the Non-Update Mode even though that box was unchecked. Might want to rethink this because sometimes out of my playing now or playlist, I might not want to process ALL files, but just one or two and clicking on those I want to process is a lot easier than loading up a playlist.
Once the lyrics get copied to MC, I noticed that there were some mistakes but I couldn't edit them. Guess if I use this, I would then need to switch to MC to edit the lyrics or the new lyrics editor plug-in.
