Little icon for page turning on the upper right gets stuck.
 

Its strange, it only happens sometimes but it does tend to block out a part of a letter once in a while, it just gets stuck there until I change the page again, anyone have this issue also?

Not sure what you mean - is it the one that looks like an open book with a line down the right side?

Is that the bookmark icon? You can clear the bookmark, then it will go away.

yes you have a bookmarked page, you need to clear it.
