Start page scrolling issues
Using the arrow key and/or page (up/down) keys has no effect on the Start page. Clicking mid window does not remove focus from the URL omnibox so using the arrow keys moves the URL selection up and down.
@jmbecker84 If you don't already have one, assign a shortcut to "focus page." I use F8 for focus URL bar, and F9 for focus page. Then you can use the cursor keys. The scrollwheel also works.
I think it's a bug. If I click on any other tab and click page down or the down arrow, it scrolls. If I click on a Start Page tab, the down arrow navigates the URL bar and page down does nothing. Scrolling with the mouse only works if you then click to focus on the internal section of the page.
