Track Sticking

Help! Why does my track stick to eachother when i have selected one track and i try to move it?

Windows 8.1, Audacity 2.1.1, I got audacity 11/11

You may have inadvertently enabled “Sync-Lock” ( Ensure that the Sync-Lock button (with the clock icon) is “up”.

Another possibility is that you are dragging from within a selection that spans both tracks. When dragging from within a selection, all tracks that are within the selection will be dragged.
