I'm not sure if the problem is really related = to Dynamic content either - I suspect I have encountered the problem earl= ier on non dynamic notebooks. Until now I just restarted Mathematica when= the problem occurred. I am reassured that I am not the only one experien= cing this problem and hope that someone has a suggestion as to what can b= e done to remedy it. > > LP > > Dear Leigh, > I also restart Mathematica. However, before I restart it, for some time= it is possible to scroll the document by moving its scroll bar. In this = case the document first jumps to the very beginning, and I have to scroll= from the beginning. It is very boring, especially in the case of large, = multipage document that I often have. Sometimes this lasts until the end = of the Mathematica session. In other cases after some time the document s= crolling freezes down definitely, and I only can restart Mathematica. > > I believe that it is a bug, and (if that is true) the aim of my post ha= s been to attract attention of Wolfram Research to this problem.

That is not quite my experience. For me the scroll bar doesn't work, except that moving it changes the size of the window. It would be good to find a way to reproduce this behaviour consistently, so that the Wolfram people could understand and fix the problem.
