GPS Data Logger Software - BT747

Since the latest update (september 2009), when pressing 'Connect' the app crashes. Happens with every port I choose. Could this be OS X version 4 specific?

I had a report recently about BT747 crashing when trying to make a connection on a Intel Core 2 Duo running "Debian GNU/Linux unstable (sid), package 6b14-1.5~pre1-3".

BT747 1.68.5 was using RxTx 2.1.7 - the currently stable version of RxTx and the crash reported:
