I recently bought a Lenovo ultabook with Windows 8.  I successfully created my first 3.5 min photo montage with jpeg images and uploaded 1 song from iTunes as background music.  Upon saving my project as the "recommended" type or to MPEG-4 the saving movie menu opens up there is no actual saving progress.  In other words, I'm unable to save this movie to any other format besides playing it fine as the project.  When I click cancel it says "movie maker has stopped working correctly and it would notify me when a solution is available".
