Videopad keeps Not Responding, Effects Screen Flashes in VideoPad Posted May 14, 2017 · Report reply Hi. I've been using Videopad for a while, just posted a few days ago about an upload problem, now I've worked that out somewhat, but another huge problem popped up. I'm editing a video and anytime I try to do an "effect," the effects screen goes white, my mouse turns into an hour glass and the effects screen flashes- from white to flat out not existing, and eventually does nothing. Please, please help. Thank you.
