Why does iMovie 11 reload my project after every edit

Question

I have had this problem from the beginning. I am working on a slide show style project (a la Ken Burns) now but this happened on smaller projects before. Typically I make a duration change to the slide and hit done. iMovie reloads the project. Sometimes it takes 1-2 seconds. Other times it acts like it is loading the project for the first time (at least 10 seconds). It's about 50/50 for doing both. Is it supposed to reload every time. I looked in Preferences (and other menus) and can't find anything to adjust. This slows my editting process to a crawl. HELP.

I think you have the wrong forum, this is for mobile devices, hence iOS Apps; I am trying to get it moved.
But as a quick answer, your final video may render out to more then 2 Gb, and your drives may not be able to handle that size files.
Check that the drive you are saving to is formatted as MacOS, and not Fat.
Even if the origonal videos are 731 mb, you may have chosen to re-compress at a higher rate.
Another idea would be to choose a lower compression, thus a smaller file.
