Treva, now that I’ve had some time to think about your issue, here’s another possible solution for you when your audio ends after a frame boundary.
Place your cursor at the end of the audio event, hold down the CTRL button and drag it back until it does line up at the frame boundary.
This will speed the audio event up but the difference is so small that you will never notice it.
This way you never have to turn off QTF.
Happy editing!
