I've just upgraded to Word 2003 SP1 and have had a little issue crop up with
the scroll button. In my previous version of Word, the scroll button
performed only its obvious function: it scrolled the open document up and
down.

Now, however, attempting to scroll the document using the scroll button
causes Word to incessantly repaginate the document.

What on earth is the link between the scroll button and repagination? Is
there any way to stop this from happening?
