Thanks JosefZ. That worked! Couldn't get /wait to work starting Windows Media Player - Cmd Processor just plowed on ahead without waiting for Player window to close. After I added a "Title" to the Start cmd, voila, I got the expected/intended results. It didn't display the title in the window but I didn't care about that, the Wait is what I was after. Peculiar indeed. (This was on Windows 11 Home V24H2)
