How to set end point, delete extra blank green space at end

How to set end point, how to delete extra blank green space at end.

There’s a big space of green at the end, how to I get rid of it? Clicking O had no effect. Clicking the ripple button worked on the video portion, but did nothing to get rid of the extra green space at the end of the audio.

There are several solutions to the green space issue here.

Those solutions didn’t work. The green space is still there.

The program isn’t working like its shown in tutorials. It won’t allow me to drag and drop, for example. I have to cut and paste, and even then it crashes.

And I’m on a new computer with windows 10.
