Can't show multiple images?

[Gumdoc]

Hi all,

Can't figure out what I'm doing wrong. I prefer to use Boxes image group for showing images. Many of my DOS games only have screenshots. So, in options, under Box Front Properties, I have Box-Front, Screenshot- Game Title, and Screenshot- Gameplay checked, in that order, plus a bunch of others after that. But, choosing the Boxes group, I still only get images for the boxes, the rest is just blank tiles. I checked some of the blank tiles, they definitely have game title and gameplay screenshots in their directory.

Here's the weird thing: I have a separate ExoDOS setup on another drive, with the same Box Front configuration...and it works exactly as intended on that drive.

Any ideas what is preventing me from viewing both boxes and screenshots when no box images exist?

Thanks for any help.
