I have never been as angry as I am right now with Apple. They have allowed a very bugged up product, Compressor/QMaster, to continue on as a defective program through three versions and two operating upgrades. It is the worst product offered by Apple and they seem to be unwilling to do anything about it. This is not the company that I so love and respect. I cannot imagine why it is not important to them. Apple, if you read this forum: Do Something to fix Compressor!
