When I get a photo and try to cut it out to be a sprite, sometimes when I click OK, the editing screen is gone but the sprite I just made is gone too! It is very tedious to cut out the images and when that glitch happens I get so frustrated when all my work is gone.
Could you describe the editing process further? How are you trying to cut out the sprite from the original image you are working with? It's easier to try to track a bug if we have exact steps to follow.
I just get an image that I downloaded or took with my camera and pretty much just erase the background with the eraser tool, so all I have is the image left. it doesn't happen all the time but when it does, It's really annoying.
