I have upgraded to Audio Studio 12. I'm having a problem. When I bring up an audio file for editing, There are two flags on the cursor. when I try and position the cursor on a part of the audio, and play that part of the audio, it goes back to the beginning, not the part I want to play. It wasn't like this when I first downloaded the program. I had to reinstall it, uninstall, then downloaded again.How can I play any part of the audio and get rid of the flags on the cursor and play any part of the audio file?
