I had DVDA3 (build 106) open all night waiting for a file to render in Vegas, then this morning when I tried to remove the main movie/title/scene from the DVDA 'Project Overview' window (Right Click > Delete), the app crashed and closed (I have the entire Windows log as well, maybe I should send it to support?):

Initial crash info presented on screen:
