UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Preview problem and Shoutbox problem

I've found references to both the AJAX related preview problem and the Shoutbox 'Sending...' problem and, although I've found what I think is the solution to the Shoutbox problem, it seems I need to get the Preview problem fixed first to validate that it's not the same root cause for both.

Does someone have a link to the Preview fix info?
