I had it happen once or twice when I first started using the program but haven’t had any trouble for awhile. When it happened to me I was doing a lot of multitasking going into the options etc…. I run karaoke and music videos also but I use an iPad for my regular music. Your computer is much better than mine also. I would recommend playing with it at home and see if you can get it to happen before a regular gig. When I first started using it I also had my other program ready just in case but haven’t had to use it in awhile. I use mine on the 2 deck setting with the video window in the middle. I don’t like using the Lyrx skin.
