I have loaded OBS Studio 20.0.1, studio mode - placed image slide show in my scene, added a folder with images I want to use. Setup hot keys, the whole 9 yards as far as I can see. When I transition to the first slide, then bring up the camera to preview - transition - then restart the image slide show it will not start using the hot keys. No advancement to the next slide. The hot action spot then moves like I am using the tab key to move through the program.
