I installed the program last week, outline worked for a couple of days but now does not function at all, either with Shift O or the Edit > FX menu. I have tried unchecking preview, tiles, changing the shape and colour etc. but nothing helps - after I click O.K a small menu briefly flashes for a second but I can’t see what it says.

- Are that color’s other channels – R,G,B – of that color also zero?
- Is that color located at index 0 in the palette?
- Is that color set as the sprite’s transparent color (
