I have found that CPU usage increases (to 100% of a processor) when scrolling text-heavy documents or (or text-heavy parts of documents), and is less when scrolling through parts of documents that have more white space and/or graphics. This is what originally led me to suspect a problem with character rendering. Can you monitor CPU usage while rapidly scrolling back-and-forth over a text-heavy document? I suppose that would have the same CPU effect as scrolling top-to-bottom of an all-text document.f Jerry
