Markers Sidebar Won't Appear

Some users report that in Sound Studio 4.11.0, the markers sidebar, which normally appears on the right side of the main window, will not appear even after clicking the button to toggle showing the sidebar.

There might be a bug which causes the markers sidebar to be set to a zero width, so it is technically “visible” but with no width. Try dragging from the edge of the window, inside the window where the sidebar might be if it had a zero width, to see if that will make it reappear.
