I am working on a very old game and have imported it into the latest version. I have been updating some of the graphics and when I do an import for a sprite, it has a black background instead of a transparent background. How do I fix this?
Check the "Transparent colour" selection in the Import Sprite window.

Ok that worked. The "Leave As Is" was selected so I changed it to top left pixel.
