When I load the Smile option, then go to paint, then press Y, it changes the sprites to lettering and etc. but how do I revert it BACK to sprites, without entirely restarting again? How I get this issue: >Create Programs with SmileBASIC >Smile button (green icon on keyboard) >Paint >Y button >Y button

Don't press Y when entering the Paint tool. The sprite and BG sheets are loaded by default, and you should only really press Y to load the font sheet or for save/load data shortcuts.

I know, I just thought there would be an option to switch between them freely...
