Report from Classic Mac OS using Apple's lame-o Java (MRJ 2.5.5).

Finally found time to install v45 (full install) on my OS 9.2.2 box at home.
Reinstalled the swing1.1.1 stuff from my 8.6 partition and it sort of works.

It connects via Ethernet and finds the unit. It downloads the databases. The playlist listing opens, but none of the actual entries in the playlist show up in the right hand pane (only time anything shows up is when you click on the empegcar entry and one entry - playlists).

Also the little arrow things don't work if the branch has not previously opened by double clicking.

Search doesn't work. Create Soup Playlist doesn't work unless you just select all (which shows up in the left hand pane, but you can't see if anything is in it since the left hand pane doesn't work).

A lot of the other stuff is working. Grab EMPEG screen, Configure player, etc.

No big deal as I usually rip on the Mac and FTP to my free/ancient PC then upload from there.

USB is 12Mb/s and 10BT Ethernet is 10Mb/s - so there is not much of a theoretical advantage for USB and in actual use I think the reports are close.
