Before: Could start interaction with NPC with UI turned off, then turn UI on while still in interaction. Now: Have to exit NPC interaction to turn UI mode on.
Also: turning screenshot mode on (UI off) defaults to displaying the hotkey list, and takes pressing F1 twice to remove. (1) Should only take F1 once. (2) Restore previous display when re-entering screenshot mode (preserve the F1 state on exit and restore when entering).
