I just upgraded to Vegas Pro 21. When I add FX to a clip the changes I am making do not appear in the video preview window until I close the Video Event FX box. This isn't like the video FX bypass on the video preview because the changes do appear when I close out the Video Event FX box. I tried the split screen view in the video FX bypass, but the same thing, the changes won't appear on the side of the screen showing the FX until I close the Video Event FX box. The applied FX appears in the preview window as soon as I close the Video Event FX box but I cannot see the changes I am making until I close the box. Please tell me how to see the FX changes I am making in real time on the video preview. I have been using Vegas for a lot of years and been through a lot of versions and have never encountered this. I assume I have something set wrong, but I can't find how to fix this. Thanks.
