[Zubersoft]

Additional changes are coming with version 3.2.1 which I'm releasing today that help with zooming issues. The change in behavior is due to the 1.5 second delay before the page is re-rendered at the higher resolution. This lets you zoom and move the page without it immediately trying to process the zoom and re-render the page while you are still interacting with it. This only applies to the HQ zoom of course, which is disabled by default. When using the single page display mode, I definitely don't see any jumping with the latest changes. The vertical scrolling display mode centers the page after it is re-rendered, so you can certainly see things jump a little bit in that mode. You can consider disabling the high quality zoom if this is an issue for you.
