I''d like to use a frameset to separate the content in an app I''m playing with into 3 separate panes. A 1/3 page width left pane will be for general navigation, (so rarely needs reloading). The main content separates into a top and bottom pane, (with the top pane being set by the nav pane, and the bottom pane being set by the top pane). Unfortunately, I''m new to
