GPS Data Logger Software - BT747

Hello!

For a while I wasn't figuring out what happened a while ago (between 2.x.1704 and 2.x.1887) which simply made gps data transfer not working with my Holux M-1000C, but yesterday I've been determined to look around the menus for new features which may have broken it and yes, there's a new device protocol called "Holux M-1000C", which was autoselected.

And it doesn't work.

Selecting old "Holux" (first option) just works.

Stopped working since last time. My command to start:

javaws http://soft.bt747.org/BT747_J2SE_Latest_RXTX2.2_Install.jnlp
And the result is:

3342 - BT747 2.X.1761 Build:BT747_mdeweerd.1761.20100729002509704
3343 - Initial: 1019x577  Screen: 1280x1024 Final: 1019x577
3344 - Linux

What is the preferred way of reporting bugs? Shouldn't there be a bugtracker? Isn't that a FAQ?

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?
