There's a bug somewhere. I have successfully done this operation hundreds and hundreds of times with previous versions of PT. The quick full-song MIDI transpose is something I do often and routinely with PT, and one of the reasons I purchased PT and it's upgrades. It's one of those workman features that you can't believe other DAWS don't have. I know this one. There's a bug. The fact that double- clicking on the pop up winow during a freeze-up opens up a notation window pretty much indicates that something is amiss.
