What Mike says. There is a bug in all recent versions, intermittent, although I don't think it adds an exact hour, here it tries to locate to the end of the timeline. For me it happens only after using audiosuite. I also think it might be caused only by pitch/time operations, but I am less certain of that. What I know is that it never happens when I am only mixing. It happens very regularly when I am doing serious editing, but not predictably. My workaround is to enter times into the smaller IN window until I can quit and relaunch PT. Here, I cannot just relaunch PT, haven't been able to do that for years because the MIDI driver breaks once PT closes, so a system restart is required in order to relaunch. It is a very annoying bug, but until someone can figure out exactly what causes it, a fix seems unlikely.
