I have downloaded the latest version, I prev. had 6.0, and when I launch new version it takes 100 secs. Have not experienced this before. Because this took so long I had thought installation was faulty so have uninstalled and reloaded 3 times without improvement. On first opening my last project (created in 6.0) opened. I set this playing and all pans and zooms extremely jerky.No such problem on 6.0. Started new project on 6.5 with same images and animation and absolutely no problem. Obviously the answer is to open older projects in relevant version but why does this happen.
