I believe Movie Maker 2012 is the latest version.  However, since I have been using Movie Maker 2012 since it first came out, how do I know I have all the updates to this version?

This is a great piece of software and as a volunteer producer for our local TV station, I want to be sure I have the latest features of MM.

One feature I appear to have a problem with (and why I want to be sure I am using the latest updates) is when I edit the source file I often lose an object (i.e. a music, narration file.)  Another example is when I move an object and it throws off the remaining content of my video (i.e. the music changes its location if I insert or delete another video or picture).  I thus have to re-check my whole video every time I insert or delete a video or picture - and this becomes frustrating when my videos are long.

Thanks,  Steve
