what's happened is i wanted to re-size the powder toy. i put it to double window size but now i can't change it back. the re-size list is of the bottom of the screen and i can't change the particles i want to place either. i tried re-downloading it but that didn't do anything. the only way i can play is if i go into my downloads and open the powder toy from there.. but then i can't use my saved stamps. if anyone can help i would be grateful!
