Use the up and down arrows to navigate; the screen will scroll in the wrong direction
Use the page up/down keys to navigate: the screen with jump by thousands of thumbnails instead of one page
Both of these are caused by the focus being wrong. When you click on the slider, the focus stays there, and the various shortcut keys operate on the slider, not the main thumbnail pane. I don't think this used to happen. We need those keystrokes to be forwarded to the thumbnail pane no matter where the focus is in the Browse Tab. For example, right now if you click on the word "Sort By" you will no longer be able to use those keys.
