Even with the most basic example file, like with GettingStartedCapture, I suddenly get the following error:
Code:

I haven't used processing in a while, but the error occured in 148, but if I open 135, is also gives the error (didn't give it a while ago).
I did install the Arduino program, and so did a friend of mine, who gets the same error.
Does anyone know what's wrong?

The applet does start and does show the webcam image btw

Im on a Intel iMac with Mac OS X 10.5.4

That's a problem with your QuickTime installation, I recommend reinstalling QuickTime to see if that fixes it.

The error message means that it has found a QuickTime component installed on your machine that's PowerPC-only, but that you're on an Intel machine (or vice versa).
