hello im kinda new here so please forgive me if i made a mistake or posted the wrong topic or something *bows*

anyway, it seems that the particles in the powder toy have become invisible. i have no idea what i did to make it this way, and now they wont come back again. the last thing i did was to click on the filters like firee or wind or heat etc and suddently the particles dissapeared. i tried to download powder toy again but it didnt work..if anyone can help me it will be much appriciated because i love playing with this little toy ;3;

oh btw, im using an intel macbook with mac os x lion in case anyone wonders...
