kbafour, I'm afraid I can't answer the question you posted ... but by golly, am I ever grateful to you for posting the information about what happens when you set that slider to "Never"! I actively use shared reviews in my workplace, and for the last few days been observing the exact phenomenon you describe - endlessly-spinning green circle, comments not published, having to save and re-open the PDF to get the comments published... and it was driving me NUTS. It was precisely a few days ago that I went through my Acrobat 9.0 Professional preferences, and adjusted the slider setting to "Never"... To use that same word again - never, ever would I have expected that changing this setting would break the publication of shared-review comments entirely!
I'd give your post a "helpful star", but the forum interface isn't offering me the option... nonetheless, definitely a star for you!
Thanks and best regards,
Same problem here. We have hundreds of projects in review, and every 24 hours my computer locks up with 500 popups in a row asking for a username and password so that tracker can automatically update. I tried setting the option to "Never" and it breaks the publish and check for new comments functions entirely. Can we get an admin at adobe to address this issue?
