    1. COI've just tried calling `os.clock()` in a script, and I'm getting an error back saying `Script attempted to access unexisting global variable 'os' `. Looks like this is unavailable. Thanks anyway!

    2. COHi Dustin, thanks for your reply. It completely passed me by that it was being called inside a block, so I have tried both your suggestions, the object is not `nil`, and `setNeedsDisplay` had no visible effect. I have also tried encasing the `[selv.webView addSubview: touchView];` in a call to `dispatch_async(dispatch_get_main_queue(), ^{});`. That didn't work either. I'll keep looking though, thank you for your help!

    3. COI've come up with a solution that is better: ScreenCaptureView handles the writing of the frames to video output at the same time, and seemingly on the main thread. I have stripped the code out so that the draw rect updates the currentScreen UIImage at the desired frame rate, and then created a subclass to write the video out on a background thread. This has allowed me to have almost smooth video at iPad resolution. I've tried this on an iPad2 and it's definitely acceptable for my needs, not tried it on a retina iPad yet.... dreading that! haha
