The beta is out, it can be downloaded at [url]http://sourceforge.net/projects/jvlt/files/jvlt-devel/100106/jVLT-20100106.jar/download[/url]. Thanks again for testing!
I'm glad that it works. If I remember correctly, loading the last opened file on startup was the default in an earlier version, but that must have been years ago. Maybe you are one of the first users :)
