Thumbnail display

When i view one of tutorial videos for studio, the thumbnails (at the bottom) display with the circle containing an x on the bottom right (for closing the image), and three little lines at the left of that circle. On my computer, the thumbnails display with only the circle enclosing the x, and the three little lines are not there. Questions-- what am i missing? and why are they not there. I am running windows 7, with studio version 1.2.8. i can also not “reset” to the original file- the undo only goes back one step.

Those options were moved to the More button in the strip above the workspace.

The reset option is just above the blend mode
