Not having fired up Vegas Pro 19 for awhile, when I loaded it today I was greeted with a requestor box stating, “HandlePIChanges”. I am up-to-date with VP 19 Build 550 and loaded the latest NVIDIA drivers for my video card. This box keeps popping up and prevents me from doing anything until I clear it. As soon as I clear it, it pops up again ad nauseum!! VP 18 Build 527 appears to work just fine, so what’s going on with VP19?
