peekdata help

Hi folks, (i've already posted this in the Answer section, not sure where is best)

I'm having a bit of trouble with peekdata.

I have a video object created called 'vid',

I'm using

RGBData = peekdata(vid,1);

This works fine, I get a 3d array in RGBData. But it only works in debug mode. As soon as I run it from the GUI I get...

"Warning: PEEKDATA could not return all the frames requested."

and RGBData is now empty... I can't understand why it works in debug but not when running normally.

thanks in advance, this is driving me nuts.

p.s. i'm trying to gather frames from a webcam indefinitely, is there's a better way to go about it?
