Map, inventory does not display

[skipperpickle]

The map viewport remains black. The displayed inventory slots remain gray, even though my character is wearing items.

[Note, I have decades of familiarity with NetHack, but this is the first time I've used NetHackCocoa, which I downloaded from the MacOS App Store.]

Update: I see now. I had to choose a tileset. It would be helpful for the game to launch with a default setting (either Use Ascii Mode on or one of the tilesets preselected).

Thanks!
