Ok, playing with this on my Powerbook is even worse. If jEmplode starts to open the empeg, the CPU is pegged at 100%. Once the databases get downloaded, it stays at 100%, and the interface is horribly slow. Opening the Karma on the Powerbook does not result in such CPU spikes.

This is using Panther, 10.3.2 and Java:
814:drakino:~>java -version
java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-117.1)
Java HotSpot(TM) Client VM (build 1.4.2-34, mixed mode)
And jEmplode v54

Another bug I forgot to report. If I open my empeg first, select another device sees the empeg again and the Karma. But, if I open the Karma first, then select another device, the empeg never shows up, even if I put the IP in the specific device option.
