I stumbled upon this oddity when upgrading to iOS 6 while working on a mobile advertising project, and it took me a better part of the day to figure out what is going on: all of a sudden an element {position:fixed} stopped working in a correct manner (which is staying put, while the page is scrolling), and started "sticking" to the scrolling page, moving out of the viewport, and then just "jumping" back to the correct location after the scrolling was finished.If you scroll this page, you will see it—hint: that's the one labeled "broken"—assuming that you have a correct device/browser combination. Mine was iPhone4 and iOS 6.0 (6.0.1-6.1.3 behaves just the same). On the original page, where I first encountered the problem, all of my elements were created dynamically using JavaScript, but at the end of the day (literally) it become clear, that the glitch is in the iOS 6 CSS implementation.Here is what happens: if you have an element {position:fixed} which has one child element {position:absolute}, the correct behavior will break, if parent element has no physical dimensions. In my case, the width of the element was omitted, and the height was set to 0px, but it breaks all the same, if they are just not specified.

Following is a short summary of the experience. I promise to keep this rant as technically oriented, as I can, in hope, that it might be of some benefit to fellow users. During nearly half of the year, which passed since my last cinematographic endevour, there were a couple of QuickTime updates, iPhoto update, and several system and security updates. Current set-up: System: Mac OS X (10.3.6) iMovie 4.0.1 iDVD 4.0.1 QuickTime 6.2 (Pro) iMac G4 800MHz 1GB RAM Good things first: audio and video ARE in synk throughout the whole 1 hour and 39 minutes of the show. I would be thrilled, if it didn't happen before, but the good thing is that it's still there. This is about it. 1. iMovie is as sl
