I purchased the software and have run it on a G5. After I run it, it produces a joined file, but locks up. I have to force quit after each use. Also, the file that is created is flawed in that the displayed length of the file is off. I have to load it into another piece of software to repair it.

The developer did respond very quickly. Nor was a refund offered. No fix has been produced yet (in about a month).
