I have reported this issue to SCS twice. To my knowlege, the problem first appeared in 10c. My reports have never been acknowledged to me by Sony. I have to assume that the issue will be fixed in 10d.
It is difficult to accept that something that has worked perfectly for me since it’s inception was broken in an update. I took the time to learn PTT and see it as a powerful part of my workflow. I use it on nearly every production that I do.
I have used Vegas professionally since the Sonic Foundry days and have never seen so many issues as in the Vegas 10 series. Sometimes I am almost afraid to hit a key for fear of a crash. Looking forward to Vegas 10d!
