Patched version 0.6.8 is ready.
It fixes the layout problem after recent changes to Pandora layout.
This is only an initial fix and an official update will come later.
Remark: The OpenPandora update mechanizm will try to load this page http://openpandora.googlepages.com/download/, but due to a problem with GooglePages it will not be recognized. The correct URL is this one http://openpandora.googlepages.com/download, without the slash (/) at the end. This is a new issue with GooglePages and I hope they will fix it soon.
Enjoy your music.
