Issue with Browser Zooming

I've had my Reality for a couple of weeks now and have started having an issue with the browser.  When I use the touch screen to scroll down a page it will sometimes initiate a zoom instead and I can't get it to zoom back out.  Am I doing something wrong?  Any ideas?

Most current web browsers use a single zoom setting for the whole page, that is both text and image. The advantage in this approach is that the web pages (which are typically designed with the lowest common resolution in mind) can be zoomed to look nice and proportional on high resolution screens. However, images that are zoomed loose their per-pixel sharpness, making them look far less impressive when users employ the zoom option.
In some browser it's possible to increase the size of the text, but this doesn't work very well as it breaks the page layout. I assume that there's no way to solve this issue and that the only thing to do is learn to accept that sharp pictures would look poor and blurry on many (if not most) user screens.
