Two simple questions, please, about Windows Movie Maker.  (1) I'm trying to fade out only the audio at a specific point.  It fades out where desired all right, but also results in a split-second drop in the audio several seconds earlier.  It seems that all the tutorial videos in YouTube are for earlier editions with different tool displays.  The help forums would be fine, but who has the patience and time to wade through hundreds of questions?!  So my second question is, (2) is there an online user manual for the latest edition of Movie Maker?  Something with an alphabetized index of on help topics?  Thanks!
