Vvvv flash - setPixel() freeze


I making flash interface to vvvv and i thought how nice to have a little preview inside it. I sending and receiving variables and this working pretty well but when i started use setPixel() in flash to draw pixels (in ‘for’ loop) my variables freeze up… Anybody know how i can fix that… I know it’s probably flash problem but maybe somebody had similar issue… (AS2)

Thanks ;)
