Hi, when a 4:3 slide show is viewed on a 16:9 screen it makes the canvas left and right of the slides black - is there a way to make this white, so it matches the slide's background? Much like viewing a 16:9 slide on a 4:3 puts the black canvas above and below the slide. I've looked everywhere and only find the obvious, how to change the slide background colour - not the canvas (or screen outside the slide). I'm guessing there's no VBA for this, but got my fingers crossed. Thank you
