I've been adding and resizing photos in the timeline of my first-ever video edit with ease. Vegas pro 20 lets you place the photo where you want it to appear in your video. I must have accidentally clicked a wrong button, because when I now add a new photo or move it to a different location or edit within the timeline, all the photos and text boxes move around the timeline at the same time. This ends up placing all the photos where I don't want them. It's easier when each photo moves by itself for editing purpose.

As you might imagine, I spent a lot of time perfectly placing each photo to hide video jumps or emphasize a point made by the spokesperson on the video. Any help is appreciated.
