I noticed in the favorites panel that I must click about one and one-half rows above the item that I actually want to click on in order to select it.
Also, sometimes (not consistently), the arrows next to folders in the Favorites list are partially obscured, or slid out to the left side of the pane, so that they are barley visible. Sorry, cannot replicate at the moment to get a screen shot. Though, it seems this behavior can be fixed by re-sizing the entire window.
