I just got painter and used it for the first time and it worked out well. How ever that was a tutorial that allowed me to work at only 72 dpi. Now I need to work on something at 300 dpi and it is running very slowly. I can't get anything done at this rate - could someone HELLLPPP!!!!!
Also, if you are on windows XP, set the skin to CLassic instead of the Regular XP skin, it will do miracles.
