Okay, I updated Hijack (I was running a couple of revs behind), and I tried disabling jEmplode's Hijack support. Neither had any affect on the symptoms I'm seeing. I can't honestly think of anything else to try. Maybe a different version of Java? What are you using? Maybe you should just come over to my house and take a look.

You know, my empeg is very near capacity; I'm having to delete stuff to upload new stuff now. Could that have an effect on any of this?
