I had one odd issue with the new version (4:3 video in a 16:9 project stretched when I went to crop it), and saw that there was a number of updates, the first of which seemed relevant to my issue. Thinking the updates were cumulative, I installed the latest update only. After that my preview window and produced videos showed only a green screen (but the trim window showed the correct video). I wound up doing a system restore back to PD8 and upgraded again to get things working once more.
I can work around the minor issue without a problem, but if an update fixes it I'd like to apply it. If the updates need to be done in sequence I'm fine with that - but if they are cumulative I suspect I'm just going to wind up restoring my system again because of the same problem. Call me lazy, but I'd rather avoid that. I'm hoping someone has a quick answer to avoid the trial and error.
Thanks in advance.
