Ken,
Thanks for validating that although I'm likely crazy, this isn't one of the reasons. It doesn't mention Analyzing Star Data in the log, but it clearly shows it onscreen. The dialog below shows "downloading" for about 16 seconds, which is normal, then shows "analyzing star data" for around 48 seconds. I had my stopwatch ready, so the actual times are accurate. The image popped up onscreen as soon as it was done downloading, but nothing proceeded for the entire time it pretended to analyze the star data. Here's a snip from the log and my second image taken tonight.

So the Analyzing Star Data pops up, but there is no green bar moving across, it's empty for the entire time (45-48 seconds consistently.)
I know you are way ahead of me in analyzing this, just sharing what I have. You guys rock!
