I'm running win7 Professional, win Live Movie maker version unknown (version is not listed under properties.  I have all the photos imported for this project, and have added music.  I want to shorten the file to fit the music.  In movie maker it plays perfectly, music is synced exactly as I want it.  Then I save the file.  When I reopen in, the file length has reverted to 6  min 22 second from the 5 minutes 17 seconds as saved and the music ends at 5 17 leaving the end of the video without music.  I have redone every step multiple times.  What am I missing?
