Rebel Galaxy Outlaw

Do the screenshot keys F3 and F4 just not seem to work for anyone else? I don’t hear a sound, nor does anything show up in the the C:\Users(myname)\Documents\my games\double damage games\RebelGalaxyOutlaw\screenshots directory on my SSD. I gather they’re supposed to end up there (and are the photos from photo mode there as well)?

Also, how does the “take video” function work from the radial menu? I invoke it, and see a 5 second countdown, which I assume is the maximum length of video clips, but again, nothing shows up in C:\Users(myname)\Documents\my games\double damage games\RebelGalaxyOutlaw\videos
