When I'm trying to read an article and I zoom in on the column of text, it can be really irritating when you scroll down the page and the whole window is shaking around due to slight left and right movements. On the iPad, there seems to be a degree of locking when you double tap to zoom, meaning you can scroll up and down the frame you've zoomed in to but slight left and right twitches won't be registered. It makes reading articles much easier. Don't suppose anyone could work out a patch for this?
