Practicing the piano I want to hear a part of a song I have selected. When I press space bar it starts to play that part and when it comes to the end it stops and returns back to the beginning of the selection. Is that possible in Cakewalk ?

Thank U Thank U Thank U Thank U Thank U Thank U It was driving me mad !

I opened Cakewalk for the first time in my life. Is there a way to stop that vertical line to stalk the cursor pointer ?
