Well, I can now answer my own question - I HAD to upgrade, so sick of not being able to keep my NVIDIA drivers up to date, since PD9 isn't compatible with them. And now, because of Cyberlink's maddening way of not allowing two versions of PD to be on a computer (the PD11 installer automatically uninstalls PD9) - I'm stuck with projects that DON'T work properly in PD11. They open, and most things work, but PiP Objects don't because the locations of the source material are different, and masks don't work for some reason -- lots of re-doing in my future in looks like.
I'll post questions in the PD11 Forum where users of this current version may be able to help.
---not a totally happy camper.
