Vegas Movie Studio 14 does not show Track Motion Button. Reading other posts, there is no "Hamburger Bun" or 3 Horizontal Lines on the left side of the video track. My View drop-down menu only shows "Window Layouts".
Hamburger menu button was introduced in a later version of VMS (16 I thought). Also Track motion button is only available in the Platinum version of VMS, not in the plain version.
