the compurter i'm using in vacation doesn't open the drawing window...i just get a tiny white square in the upper left side of the window with coloured little cubes and cones in it ...i changed the cookie-settings but i still doesn't work...
does anyone know how i can fix this?

I think you must download the java plugin, if your computer cannot run java programs. >:)
