This bug was really nasty. Took some time to get it, together with the side effects. A new version with bug fixes and added features can be found: http://mygogrinder.sourceforge.net/download.html
I've named it version 0.5.0 .The last-card-problem is gone, the lost-card-problem either, you can reset the settings, if the program doesn't anymore start, and some more bugs are gone. I added also some features, e.g. nice sound for right/wrong, some more categories, problem files, it remembers the last directory, you can switch the look&feel (not important, just playing with the code), and...

Maybe Ross takes the code on his page?

For the latest version of my fixes see https://sourceforge.net/projects/mygogrinder/files/
I've uploaded JsekiTsumego 0.5.1-b141.jar
More problems, nice sound.
