So sorry… but toggling “ignore event grouping” has no effect (..tried that before my post!). Using “alt”, “ctrl+alt”, and “ctrl” allow me to move music within the envelope, but as soon as I try to resize the music, it affects the video portion. In fact, it splits the video at seemingly random portions of the slide show unless I try to resize it at the very beginning, which always moves the entire video and audio. If I try to resize the audio at the very end, it selects one of the pictures in the video at random and overlaps all of the rest of them.
I finally resolved the problem by moving the audio within the envelope using “ctrl+alt”, then splitting the audio using “s” at the end of the clip and deleting the unwanted portion of the audio created by the split, but there has to be a better way! The beginning of the clip is still only marginally acceptable!
Any suggestions are greatly appreciated. Thanks in advance!.. Paul
