Well, after nearly two months,without any obvious explanation, my journals have begun to publish. I know not why. A week or so ago I got word through my "case worker' that this problem had been "escalated" after the team had finally been able to reproduce the problem and could NOW see that it was a REAL problem....vindicated, I guess.
Anyway, I've now created a few new (junk / trial) journals and been able to publish them and the largest journal, the one that started all this for me, has begun to publish again.....
I wish I could convey something that would help others, but I really have NO IDEA what happened to change things. Maybe I'll learn something in the coming week.
I'm not sure if the version of iPhoto has changed. It was updated a while back, but I had tried publishing unsuccessfully after the last KNOWN update. I'm now running v 1.1(293).
This is really a relief as I'm making plans to leave on another trip soon and had almost lost hope of using iPhoto to record the outing. At any rate, I'm going to continue to test through the coming week (or more) to be sure this is for real, but it does look encouraging.
I hope you all have similar experiences SOON.
