I'm having a anomaly when altering the pixels of a UIImage, I've drawn a box and then I've colored every pixel of the image with a light blue, so the box should forever be gone right? Wrong!

What you'll see is the screen being fully blue, then the box showing it's unwelcome face up in a few seconds, then the screen becomes fully blue, going backwards and forwards.

I'm thinking this maybe something to do with the CGContext, does this store the paths I used previously to fill in a poly?

I've supplied the a cut down version of my project that will demo my problem, it's triggered by a touches finished, so you will have to click down to see the show.

Thanks in advance.
