Howdy,

Hmmm... no scrolling problem here. What are your settings in the Preview tab of  TeXShop->Preferences? Especially, what is the setting for the Default page Style? If you have it as Single Page you would see that behavior. make sure it's set to Multi-Page (or Double-Multi-Page if that's your preference).

Good Luck,

Herb Schulz
