Is this a bug - not sure? I had to revisit a project to create a projector and when trying to do this with the latest version all of my start positions were lost and initial visual positions reset to default. The projector version sized itself at about 105% so that there was some cropping. Fortunately as a Mac user I was able to hop in the Time Machine and resurrect the version of the app used to create the project. Projected via that version and everything was back to where it should be.
From now on I shall create projector versions of each project as they are created - just in case they are needed in future. I don't know if this is a bug or expected behaviour - it's all beyond me and I'm just grateful that FFC lets me do things that otherwise just wouldn't be possible.
