My theory is that Pinnacle intended to make the screenshots scroll through each photo as I have been told that it could be a corrupt file/install and was requested to reinstall the whole program again.
Welcome to first level Pinnacle support. Their answer to anything they don't understand is to re-install the program.
I've had personal experience of this in at least two cases, where in fact the problem has been a repeatable bug in the program. If you keep talking to first level support, they will keep telling you to reinstall, or try it on another computer.
If your theory is correct, then every single S12 disc and the download version is corrupt.
.....and why then does the "Opening" montage only pass by the first photos, but zooms in fully to the last drop zone?
