Well, I'm still confused a little about the text flow. If you put the cursor after the last character on the page before the blank, and pres the right arrow key once, where is the cursor? Is it visible on the next page that shows text?
OS is not a problem for the update, and there were a LOT of bug fixes. Unfortunately, if this wasn't one of the things that did get fixed you're stuck becasue there won't be any more updates to CS5.5.
